With over 10 million known chemicals, and potentially dangerous results if chemicals are combined in an incorrect manner, imagine the problem if you are in the lab and say "mix 10 grams of that stuff in with this stuff". Organic compounds were associated with living organisms, however, a large number of organic compounds have been synthesized which do not occur in nature, so this distinction is no longer valid.
The positive ion (cation) is always named first and listed first in writing the formula for the compound. An older nomenclature for distinguishing between the different ions of a metal is to use the suffixes -ous and -ic.
Note that the different ions of the same element often have quite different chemical properties (again, pointing to the importance of electrons in determining chemical reactivity). Note that unlike the -ous and -ic suffix nomenclature to distinguish the different cations of a metal, the -ite and -ate suffix is used to distinguish the relative amounts of the oxygen atoms in a (polyatomic) oxyanion (in the above examples the ionic charge is the same for the -ite and -ate ions of a specific oxyanion). Note again, that the number of Oxygens relative to the Chlorine is changing, but that the ionic charge is not. It should be pointed out that some of the naming of ions is historical and is not necessarily systematic. Many polyatomic anions that have high (negative) charges can add one or more hydrogen cations (H+) to form anions of lower effective charge. The formula of an acid consists of an anionic group whose charged is balanced by one or more H+ ions.
Using the -ic suffix here may seem a bit inconsistent since it was used in naming metal cations to indicate the form which had the higher positive charge. This is confusing: we previously had used the -ous and -ic suffixes to indicate the ionic charge differences in metal cations (-ic had a higher positive charge). Although they may not be ionic compounds, chemically bonded compounds of two different elements can be thought of as being made up of an element with a more positive chemical nature, and one that has a more negative nature in comparison.
Such prefixes can extend for quite a way for some organic and polymeric compounds (a common detergent in shampoos is sodium dodecylsulfate, or "SDS", also known as Sodium Laurel Sulfate because it sounds more benign and holistic). In the 19th century, Lord Kelvin created the Kelvin temperature scale to measure very low temperatures.
The Stefan-Boltzmann law, a fundamental law of physics, explains the relationship between an object's temperature and the amount of radiation that it emits. E represents the maximum rate of radiation (often referred to as energy flux) emitted by each square meter of the object's surface.
Consequently, Wein's law explains why the hot sun emits radiation at relatively shorter wavelengths, with the maximum emission in the visible region of the spectrum, whereas the relatively cool Earth emits almost all of its energy at longer wavelengths in the infrared region of the spectrum. Understanding the basic mechanism of heat transfer within Earth's atmosphere and between its surfaces (land and water) and the atmosphere will help you learn how Earth's energy balance works to regulate our climate.
Heat is energy in the process of being transferred from one substance (or object) to another. Conduction is the direct spread of heat from a warmer substance (in this case, land or water) to a cooler substance (the atmosphere).
Another type of important heat transfer process affecting the climate system occurs when water undergoes a change in phase. When water changes phase, heat is exchanged between the water and its surroundings — the water either absorbs or releases heat depending on the phase change. SUMMARY: The jovian planets are essentially big balls of gas, each surrounded by many moons and rings. Jupiter, Saturn, Uranus and Neptune collectively make up the group known as the jovian planets.


Unlike the spherical shapes of terrestrial planets, the jovian planets are all slightly oblong. Observations of clouds at different latitudes suggest that the jovian planets rotate at different speeds near their equators than near their poles. After size, perhaps the most noticeable difference between the jovian and terrestrial planets involves moons and rings.
All four jovian planets have rings, although only Saturn's rings are easily visible from Earth.
While terrestrial planets accreted from planetesimals made of rocks and metals, they ended up too small to capture significant amounts of the abundant hydrogen and helium gas in the solar nebula.
The atmospheres of Jupiter and Saturn are made almost entirely of hydrogen and helium, although there is some evidence they contain hydrogen compounds. The cores of all four jovian planets are made of some combination of rock, metal and hydrogen compounds.

However, when you think about it, the acid compound has a higher net positive charge than the anion from which it is derived (the anion is negatively charge and the associated acid is neutral).
Although in comparison to the ionic form, the -ic and -ous acid forms have a higher net positive charge, the -ic suffix would indicate forms with a higher oxygen content, and not an apparent charge difference.
Elements on the left hand side of the periodic table prefer to donate electrons (thus taking on a more positive chemical nature), and elements on the right hand side prefer to accept electrons (thus taking on a more negative chemical nature).
Because zero Kelvin is considered to be the lowest temperature possible, it is described as absolute zero. For example, when a stovetop burner reaches 1,000 Kelvin (K) — 726° Celsius (C) or 1,340° Fahrenheit (F) — it will glow red. An object that absorbs and emits all possible radiation at 100 percent efficiency is called a blackbody.
For this reason, solar radiation is often referred to as shortwave radiation, and terrestrial radiation as longwave radiation.
Convection is the spread of heat in a fluid, defined as a gas or liquid in which atoms and molecules are moving relatively freely.
We can sense the resulting change in temperature, so these heat transfer mechanisms are known as sensible heating.
In other words, it changes from a liquid, solid, or gas (water vapor) into a different form or phase (melting ice is an example of a phase change). This type of heat is called latent heat, because that heat is stored or hidden until the phase change occurs. This energy that is absorbed gives the molecules the extra motion that is needed to escape the surface of the liquid to become a gas. The general structures of the jovian planets are opposite those of the terrestrial planets. The terrestrial planets are nearly isolated worlds, with only Earth (1 moon) and Mars (2 moons) orbited by any moons at all.
Rings are composed of countless small pieces of rock and ice, each orbiting its planet like a tiny moon.
The jovian planets, however, formed farther from the Sun where ices and rocks were plentiful.


Uranus and Neptune are made primarily of hydrogen compounds, with smaller traces of hydrogen, helium, metal and rock.
This means that the same gases will condense to form clouds at different altitudes on different planets because the condensation of a gas requires a specific amount of pressure and temperature. Jupiter and Saturn have similar interiors, with layers extending outward of metallic hydrogen, liquid hydrogen, gaseous hydrogen, and topped with a layer of visible clouds.
For this reason, the following two laws (Stefan-Boltzmann and Wein's laws) can be used to explain the correlation between temperature and radiation for the sun and Earth.
The W refers to watt, which is the unit used to express power (expressed in joules per second). The higher the object's temperature, the faster the molecules will vibrate and the shorter the wavelength will be. When Earth absorbs the sun's energy (most of which arrives in the form of visible light), the energy changes into heat.
Therefore, conduction, as a heat transfer mechanism, occurs at Earth's surface where the air is in direct contact with the surface. The reason that heat is transferred as water changes phase is due to the hydrogen bond between molecules of water. This process is known as evaporation, and the absorption of heat is called the latent heat of evaporation (or latent heat of vaporization).
Rather than having thin atmospheres around relatively large rocky bodies, the jovian planets have relatively small, dense cores surrounded by massive layers of gas. Gravity by itself would make a planet spherical, but their rapid rotation flattens out their spherical shapes by flinging material near the equator outward. Unlike Jupiter and Saturn, Uranus and Neptune have cores of rock and metal, but also water, methane and ammonia. Temperature is a measurement of the average speed of the atoms and molecules that make up a substance. Extra energy is needed to break this strong bond and change water from one phase to another. The latent or hidden heat is then released, which is why this process is known as the latent heat of condensation.
The rings are located closer to the planets than any of their moderately sized or large moons, but the inner edge of the rings is still well above the planet's cloud tops. You can see from the graph to the right that these condense at lower altitudes in Saturn's atmosphere than they do in Jupiter's atmosphere. The layer surrounding the core is made of gaseous hydrogen, covered with a layer of visible clouds similar to Jupiter's and Saturn's. Because the atmosphere is heated from below, the temperature in the troposphere decreases with height. As air or water warms, it expands and becomes less dense than the air or water above, and it rises.
Heat energy is also spread throughout Earth's atmosphere through conduction and convection.
Beyond the frost line, where hydrogen compounds could condense, the solid particles included ices as well as metal and rock.
