Helium does not form ion.
An ion is an atom with a positive or negative charge.
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.
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+.
Removal of an electron from an atom leaves a positively charged ion.
An atom with an electrical charge is called an ion.
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 of potassium-41 becomes a potassium ion with a plus charge by losing one electron. Potassium-41 has 19 electrons in its neutral state, but when it loses one electron, it becomes a potassium ion (K+) with a plus charge and 18 electrons.
Removal of an electron from an atom leaves a positively charged ion.
An atom with an electrical charge is called an ion.
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!
Yes, a helium atom is electrically neutral because it has an equal number of protons, which carry a positive charge, and electrons, which carry a negative charge. The positive charge of the protons cancels out the negative charge of the electrons, leading to a net charge of zero.
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 ."
The particles that affect the charge of an atom or ion are electrons and protons. Electrons have a negative charge and protons have a positive charge. The number of electrons and protons in an atom or ion determines its overall charge.
