In order for atoms to form bonds they have to either give out electrons to another atom(ionic bonding) to form oppositely charged particles that will attract or they have share electrons electrons (covalent/metallic bonding).
Helium and Neon are group Zero/Eight elements, they have a full outer-shell, so they don't need to give up their electrons or to find more electrons. They are happy as they are extremely stable.
Helium has one full shell, so therefore there is a small ATOM RADIUS as the shell is close to the nucleus, this means there is a greater nuclear attraction, also the outer electrons of Helium experience less ELECTRON SHIELDING as all the electrons are in one shell. Overall because it is difficult to loose its first electron (as there is a greater nuclear attraction,) Helium they cant form bonds with other atoms as it doesn't want to share or give out its electrons.
Neon Is similar to this, but it has a slightly greater ATOMIC RADIUS than Helium, so the nuclear attraction isn't as great, It will experience more slightly more ELECTRON SHIELDING as its has two shells and the inner shell electrons repel the outer electrons, but since Neon has more protons and electrons than Helium it has a stronger NUCLEAR CHARGE which in turn increases the nuclear attraction making it difficult for Neon to loose its first electron, thus cant share electrons to form a bond.

They are helium atoms and have all the properties of helium. Helium is mono-atomic [as are all of the noble gases] Non-noble gases [those gases that react with other elements/compounds] are diatomic meaning that in the gaseous state the atoms are paired on to another.
The noble gases stay single. These include Helium, neon, argon, krypton, xeon, and radon.
No, helium is not a hydrocarbon. Helium is a noble gas and is chemically inert, meaning it does not readily react with other elements to form compounds like hydrocarbons which contain carbon and hydrogen atoms.
No. Helium is one of the "noble" gasses, and they generally don't react with much.
no. lead doesnot react with helium

Helium will not react with any other element.

Helium does not react with any elements at normal circumstances because all the vacant spaces of the outer electron shell are filled. It will not normally give up or gain electrons but ions of helium may react with other elements.
Helium does not react with other elements. It is a noble gas and has a full outer shell of electrons. Because it is not seeking to gain or lose any of its electrons, it will not react.
No, helium is not a hydrocarbon. Helium is a noble gas and is chemically inert, meaning it does not readily react with other elements to form compounds like hydrocarbons which contain carbon and hydrogen atoms.
When heated, chlorine will dissociate into chlorine atoms and helium will remain as a noble gas. The chlorine atoms will react with any available species present in the system.
No. Helium is one of the "noble" gasses, and they generally don't react with much.
The most stable atom is helium because it has a full outer electron shell, which makes it less likely to react with other atoms.
Atoms of non-metals usually gain or share electrons when they react with other atoms.
Correct Helium can form unstable compounds (excimers).
