An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
A Co3+ ion has lost three electrons from its neutral state, so it has 23 electrons.
The phosphate ion is a polyatomic ion with a total charge of -3. This means it has gained 3 electrons to achieve an overall negative charge, so it has a total of 30 electrons.
Ba2+ ion has a total of 56 electrons. Barium (Ba) has 56 electrons in its neutral state, and when it loses two electrons to become Ba2+, it now has 54 electrons remaining.
A chloride ion (Cl-) has a total of 18 electrons. This includes the 17 electrons in a neutral chlorine atom, plus the extra electron gained to achieve a stable octet configuration.
An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
The H+ ion has no electrons.
A Co3+ ion has lost three electrons from its neutral state, so it has 23 electrons.
Chlorine will not for Cl-7 ion. It will form Cl-1 ion, which has total of 18 electrons.

A sodium ion with the symbol Na+ has 10 electrons. Sodium normally has 11 electrons, but when it loses one electron to form a Na+ ion, it has 10 electrons.
The element that forms a 3+ ion with ten electrons is sodium (Na). Sodium has 11 protons and normally has 11 electrons, but when it loses 3 electrons to form a 3+ ion, it has a total of 10 electrons.
A cesium ion with a +1 charge (Cs+) has lost one electron. Cesium (Cs) normally has 55 electrons, but the Cs+ ion has 54 electrons.
A Be2+ ion has 4 protons and 2 electrons. Be2+ ion is formed when beryllium loses 2 electrons, resulting in a 2+ charge on the ion.
