an atomic number of 2 and an atomic weight of about 4. So it has 2 protons, 2 neutrons, and 2 electrons. It has a complete valence shell (the smallest atom with this attribute) which makes it the smallest noble gas. It has a cas# of 7440-59-7... I'm not sure what you're asking. I can go on but it would be better if you'd ask a more specific question. You can email me too.
Helium atom has 2 electrons.
Helium is an element- the second one in the periodic table.

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+.
If you build an atom using two protons, two neutrons and two electrons you would build an atom of Helium. To be more-precise, this would create Helium-4 the common isotope of Helium.
Elements are not species. Helium is an element. Helium can be a single atom.
Helium atom has 2 electrons.
Helium is an element- the second one in the periodic table.
Yes, helium atom.
A neutral atom of helium has 2 electrons.

Helium will not react with carbon as helium is chemically inert.
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+.
Helium is a neutral atom that has several isotopes and can become an ion.
The nucleus of a helium atom contains two protons and two neutrons.
If you build an atom using two protons, two neutrons and two electrons you would build an atom of Helium. To be more-precise, this would create Helium-4 the common isotope of Helium.
Helium has one kind of atom: helium.
