Oxygen has eight total electrons — two orbit the nucleus in the atom's inner shell and six orbit in the outermost shell. The outermost shell can hold a total of eight electrons, which explains oxygen's tendency to react with other elements: Its outer shell is incomplete, and electrons are...
Commercial production of nitrogen is largely byfractional distillationof liquefied air. The boiling temperature of nitrogen is −195.8°C(−320.4 °F), about 13 °C (−23 °F) below that of oxygen, which is therefore left behind. Nitrogen can also be produced on a large scale by burnin...
The cleanest way to produce hydrogen, however, is through splitting water into hydrogen and oxygen by using sunlight, the NREL reports. Additional resources Here is more info on hydrogen from the Los Alamos National Laboratory. Here is what the Jefferson Lab says about hydrogen. The Royal ...
It consists of two hydrogen atoms covalently bonded to a single oxygen atom. In the majority of cases, the reaction between oxygen and another element is extensively exothermic. One of the most well-known of these reactions is the one that occurs between carbon and oxygen, producing carbon ...
Atomic mass unit (AMU), in physics and chemistry, a unit for expressing masses of atoms, molecules, or subatomic particles. An atomic mass unit is equal to 1 12 the mass of a single atom of carbon-12, the most abundant isotope of carbon, or 1.660538921
Carbon is the fourth most abundant element in the universe (hydrogen, helium, and oxygen are found in higher amounts, by mass). It is the 15th most abundant element in the Earth's crust. Carbon usually has avalenceof +4, which means each carbon atom can form covalent bonds with four ...
Water is made of three atoms, an oxygen atom and two hydrogen atoms, and thus is both a molecule and a compound. A chemical formula is an abbreviation that shows which atoms are in the molecule and in what quantity. For example, the chemical formula for water is H2O. This means that ...

Hydrogen is the first element in theperiodic table, meaning it has anatomic numberof 1 or 1 proton in each hydrogen atom. The name of the element comes from the Greek wordshydrofor "water" andgenesfor "forming," since hydrogen bonds with oxygen to form water (H2O). Robert Boyle produced...
Atomic Hydrogen (H) is the first element in theperiodic table. It is a free radical, with a single proton and a single unpaired electron. However, a hydrogen atom rarely exists on its own due to the eagerness of its unpaired electron to pair up with another electron. ...
