Elements are not species. Helium is an element. Helium can be a single atom.
An atom of helium has 2 electrons.
Yes, 1 helium atom is an atom. Helium is an element, and each helium atom consists of a nucleus with 2 protons and 2 neutrons, surrounded by 2 electrons.
When a helium atom loses an electron, it forms a helium ion which is positively charged because it has one less electron than protons. This helium ion is written as He+.
Yes, helium atom.
A neutral atom of helium has 2 electrons.

Helium will not react with carbon as helium is chemically inert.
The nucleus of a helium atom contains two protons and two neutrons.
Helium is a neutral atom that has several isotopes and can become an ion.
