Noble gases or inert gases have electron configurations that are very stable.
Helium 1s2
Neon [He] 2s2 2p6
Argon [Ne] 3s2 3p6
Krypton [Ar] 3d10 4s2 4p6
Xenon [Kr] 5s2 4d10 5p6
Radon [Xe] 4f14 5d10 6s2 6p6
Helium has a full energy shell, as does neon. The rest have partially filled outer shells but with the s2p6 configuration seen in neon (the "octet")
What this tells you is that He, Ne should be really stable but that the others may be persuaded form compounds, if you tried hard enough. Compounds of xenon were the first to be made in the 1960s, the xenon fluorides. Compounds for Krypton are known and very recently some really unstable compounds of Argon.

How does atoms combine to form molecules?
They can combine in lots of ways. Some reactive elements will combine on their own but others need heating to combine. Noble gases (krypton, argon, xenon, helium, neon and radon) do not react (combine) with other atoms.
What is the relationship among atoms elements and molecules?
atoms combine to form molecules of elements
What atoms form when they combine together?
They create molecules. If the atoms joined together are from different elements they create polar molecules.
Combined atoms form what?
Well, they can form molecules. Molecules join together to form elements. Elements join together to form compounds.
How do atoms combine to form molecules through ionic bonding?
Atoms do not form molecules through ionic bonding. They form molecules through covalent bonding, in which the atoms share electrons.
What combine to form molecules?
atoms
What do atoms form when combine?
Molecules.

What is the relationship among atoms elements and molecules?
atoms combine to form molecules of elements
Do molecules combine to make atoms?
Not really. Molecules are combinations of atoms formed when they share electrons.
Can molecules combine to form atoms?
No. Atoms bond to each other to form molecules, not the other way round
What atoms form when they combine together?
They create molecules. If the atoms joined together are from different elements they create polar molecules.
Are all atoms made up of molecules which may combine to form elements?
No. Molecules are made of atoms, not the other way around. Atoms of different elements combine to form compounds.
Combined atoms form what?
Well, they can form molecules. Molecules join together to form elements. Elements join together to form compounds.
Why atoms join to form molecules?
atoms are generally unstable. they combine to form stable molecules
How do atoms combine to form molecules through ionic bonding?
Atoms do not form molecules through ionic bonding. They form molecules through covalent bonding, in which the atoms share electrons.
What can predict how atoms combine to form molecules?
periodic table..
