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.

What is the ion charge of a helium atom Is it plus 1?
Helium does not form ion.
When an atom gains an electron what charge does it have?
An atom that gains three electrons will become an ion with a 3- charge.
How does an atom become a positive ion a nevative ion?
When an atom loses a negative charge, when it loses an electron, it becomes a positive ion.
Is an ion atom with a charge?
An ion is an atom with a positive or negative charge.
A molecule is an atom that has gained or lost an electron?
The answer is simply an "ion." The atom itself cannot be named until it has gained or lost an electron, in which it has lost an electron to become more positive, it would become a cation. If the ion had gained an electron to become more negatively charged, it is then named an anion.
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.

What happens when a atom losses a electron?
The neutral atom become an ion (cation) with the charge +1.
A molecule is an atom that has gained or lost an electron?
The answer is simply an "ion." The atom itself cannot be named until it has gained or lost an electron, in which it has lost an electron to become more positive, it would become a cation. If the ion had gained an electron to become more negatively charged, it is then named an anion.
