Helium does not form ion.
A regular helium atom (He) has no ionic charge. The element in its standard form as it appears on the period table and in our everyday environment has two protons and two electrons. The positive charge of the protons cancel out the negative charge of the electrons, and so there is no charge left. Furthermore, helium is a noble gas, a family of elements which are extremely stable and will not react with anything under normal circumstances. If, however, an atom of helium where ionized in a lab, and stripped of its electrons, it would have a charge of plus two.
An ion is an atom with a positive or negative charge.
An atom with an electrical charge is called an ion.
Type your answer here... when helium atom removes a electron it forms a helium+ ion.(He+)
Barium has two electrons in its outermost shell, electrons carrying a negative charge. When the Barium atom becomes an ion, these two electrons are lost. Now the Barium atom has more protons than electrons, meaning a net positive charge of 2.
Helium is a neutral atom that has several isotopes and can become an ion.

For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.

An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."

It depends on the charge of the atom/ion however in a no-charged state Helium will have 2 electrons. If the Helium is charged negatively will have more. If it is charged possitively (up to 2+) it will have less. As Helium is a noble gas, it is rarely found in a charged state!
When an atom has an electric charge it is called an ion.
