Helium Neon Argon Krypton Xenon Radon

These are the nobel gasses which have their out electron shells full and thus don't bond easily with other atoms. Argon makes up almost 1% of the atmosphere.

How do atoms of oxygen and hydrogen differ?

A hydrogen atom is made from one proton and one electron. An oxygen atom has 8 protons and 8 electrons. Hence their "Atomic Numbers" are "1" for hydrogen and "8" for oxygen. However their "Atomic Weights" are 1 for hydrogen and approximately 16 for oxygen because, in a normal atmosphere, hydrogen exists as a gas cloud of single atoms whereas oxygen exists as a gas cloud consisting of pairs of atoms.

Do molecules make up elements?

When an element is referenced, it normally is considered as a single atom, as in the periodic table.When elemental material is referenced, it is considered in aggregate form (assemblies of like atoms). For example: elemental hydrogen normally exists as a molecular gas, two atoms comprising each molecule; elemental Iron normally exists as large numbers of iron atoms in an aggregate, crystalline form (iron metal).

What type of bond holds two hydrogen atoms together in hydrogen gas?

The bond holding the diatomic molecule of hydrogen (which exists in hydrogen gas) is a single covalent bond. This is the sharing of one electron in their 1s orbital, forming an stable electron that of helium: 1s2


Is pure air an element or a compound?

If you are talking about the gas we breath in the air, it's a compound. Pure oxygen as a gas exists as a molecule. Oxygen as an element, is unstable and as far as I know doesn't exist as a single element in nature. It will always occur in combination with something else, such as H2O or O2.
