yes because it is a noble gas the same as He(helium) Ar(argon) Kr(krypton) Xe(xeon) and Rn(radon) because they all have a fuller outer shell
If you are wondering which of these exists as a single atom, LOOK SOMEWHERE ELSE!
it does not have 1 but 10 so it is a compound
No, Neon gas is made up of a single type of isolated atoms each denoted by Ne.
It's neither, but it's an element.
because neon is anoble gas
yes
There are two naturally occurring isotopes of helium: He-3 (which is very rare, comprising 0.00014% of naturally occurring helium), and He-4 (which comprises the other 99.99986%of naturally occurring helium). Whether helium is one type of atom or not then depends on the definition of "one type of atom"; if He-3 and He-4 are considered different types of atom due to their differing numbers of neutrons, then no, helium is not one type of atom; if He-3 and He-4 are both considered the same type of atom due to their common number of protons, then yes, helium is one type of atom.
Elements
No, helium is a pure substance and an element to be more specific. It has a constant composition making it a pure substance and it is homoatomic (has only one type of atom) which makes it an element.
Helium is an element- the second one in the periodic table.
7 Helium contains two electrons in all naturally occurring states.

Helium is an element because it contains only one atom in its simplest form.
"Atom" implies there's only one there. If there were more than one atom, you'd have a compound. Since helium's an element, all that's in it is helium.
One atom is too small to see. A helium atom is the smallest type of atom.
A pure substance made of only one type of atom is an element.An element, or elementary substance.An element.

Elements with only one type of atom: Mercury (Hg), Iron (Fe), Helium (He), oxygen (O or O2), bromine (Br or Br2) Elements with more than one type of atoms: Water (H2O), carbon dioxide (CO2)
Helium has only one type of gas (which is helium itself)
because it only has one orbital
