An overview about the chemical element Plutonium
By: Melanie Grimes
Plutonium is named after the Greek god Pluto, the god of the underworld. He was the god of ghosts and spirits. The planet was named for the planet Pluto, now thought to not be a planet after all.The element was discovered in 1930 and...
An overview about the chemical element Tungsten
By: Melanie Grimes
The name of tungsten is derived Swedish words tung meaning heavy and sten meaning stone. Tungsten was discovered in 1783. Because it is often referred to as Wolfram, it has the chemical symbol W. Wolfram is named after the mineral wolframite, because that is where...

Almost uniquely in the natural world, the coldest forms of water ice float on top of warmer forms of water, because ice is less dense than liquid water. Upon this simple natural law, all life on our planet depends.The ratio of an object's mass...
An overview of the chemical element Hydrogen
By: Melanie Grimes
HydrogenHydrogen was the first element created after the big bang. It holds first place in the periodic table with the atomic number of one. Robert Boyle produced hydrogen gas as early as 1671 during an experiment with iron and acids. Though scientists were producing hydrogen...
An overview about the chemical element Gold
By: Melanie Grimes
Gold has an atomic number of 79. Its name is from the Sanskrit word Jval and the Anglo Saxon word for gold. Its chemical symbol, Au, is from the Latin word for gold, aurum, which means yellow. Use of gold dates back as far in...

The ideal gas law predicts the state of a gas at a given pressure and temperature. It is expressed mathematically as PV = nRT, where P represents pressure, V represents volume, T represents the absolute temperature in Kelvin degrees, n is the amount of gas...
An overview about the chemical element Gadolinium
By: Melanie Grimes
Gadolinium is a rare earth metal and a member of the lanthanide family. The lanthanides are soft silvery metals, whose name means "hidden". They are very much alike and hard to distinguish from each other. They are members of the rare earth metal group, but...
An overview about the chemical element Europium
By: Melanie Grimes
Europium was discovered just over one hundred years ago, in 1896, when the French chemist, Eugne-Antole Demaray was investigating the newly discovered element of samarium. His samarium samples were contaminated, and on further investigation he found the contamination was an unknown element. He was able...

A candle consists of two primary components: a wick, and the solid fuel into which the wick is embedded. The wick must consist of some material which can catch fire quickly and which is also absorbent. In contrast, the fuel must not be able to...

Boyle's Law states that at a fixed temperature and within a closed system, the volume of a fixed quantity of a gas is inversely proportional to the pressure it exerts: PV = k, where k is a constant. For example, the volume of air in...
