This atom become a cation with a +2 electrical charge. All atoms have are neutral because the numbers of protons and electrons are equal. When you subtract any number n of electrons, the new charge is +n, just as a general rule.
This atom become a cation with the electrical charge +2.
An atom that loses two electrons will form a cation with a +2 charge. For example, sodium can form a Na+ cation by losing two electrons.
When an atom becomes an ion with a 2+ charge, it means that the atom has lost two electrons, resulting in more protons than electrons. This gives the ion a positive charge since protons are positively charged particles. The ion will now be attracted to other particles with a negative charge to achieve stability through the formation of ionic bonds.
An electron can be gained or lost from an atom for two reasons: 1. A random number of atoms can be close together will have electrons bumping into each other. Since all electrons have a negative charge, they will have magnetic effects on one another, and will push eachother of the outer shell of their atoms and into different ones. 2.Two or more atoms can bond together so that both atoms in turn have a balanced number of electrons.
The charge of nickel when two electrons are lost is +2. When nickel loses two electrons, it becomes a cation with a charge of +2.
This atom become a cation with the electrical charge +2.
+2 is the charge represented Cu2+
They are lost. If it has a plus sign beside the ion charge, that means the atom loses electrons. But if it has a negative sign for the ion charge, that means that the atom gains electrons.
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.

As written, there's some ambiguity in the question, but the answer is probably "+2" assuming the atom was neutral to start with and that the two outer-shell electrons were the only electrons lost.
Most atoms are electrically balanced because they have the same number of protons, which have a charge of +1, and electrons, which have a charge of -1. However electrons can be lost or gained. When they are, the atom has a different number of protons to electrons so it becomes charged. Example. An uncharged atom of oxygen has 8 protons and 8 electrons. Sometimes it gains two electrons. This means that it has 8 protons but 10 electrons. +8 -10 = -2. therefore the charged atom of oxygen has a charge of -2.

A calcium atom has 20 electrons, as it has 20 protons to maintain a neutral charge. A calcium ion, specifically Ca2+, has lost two electrons, so it has 18 electrons.
A calcium ion with a 2+ charge (Ca2+) has lost two electrons. A neutral calcium atom (Ca) has 20 electrons, so Ca2+ would have 18 electrons.
