Helium atom has 2 electrons.
It depends on the atomic weight and how many positive, negative, and neutral charges are in the atom. Marshmellows!
A neutral atom of helium has 2 electrons.
Helium has one kind of atom: helium.
Something is neutral when there are just as many positive charges as negative charges. A normal atom has just as many positive protons in its nucleus as it has negative electrons orbiting around its nucleus.
Helium has 2 positive protons in its nucleus.
Boron typically has three positive charges (protons) in its nucleus, thus making it a positively charged ion.
