This atom become a cation with the electrical charge +2.
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.
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.
In oxygen, each atom gains two electrons to achieve a stable electron configuration through forming two covalent bonds. This means that each oxygen atom gains two electrons to reach a full valence shell.
A Mg2+ ion has lost two electrons compared to the neutral magnesium atom. As a result, it has 10 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.
The chemical symbol for a magnesium atom that has lost two electrons is Mg2+.

An atom that carries an electrical charge because it has gained or lost electrons is called an "ion". An atom that has gained one or more electrons, and has a negative electrical charge, is called an "anion". An atom that has lost one or more electrons, and has a positive electrical charge, is called a "cation". The term "ion" is used to refer to both cations and anions collectively or non-specifically.
One atom has lost electrons . And the other atom has gained electrons.
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.
The outermost electrons, found in the highest energy level, are the most likely to be lost in a magnesium atom. Magnesium has 2 electrons in its outermost energy level, so it tends to lose these electrons to achieve a stable electron configuration.
Two or three electrons are lost.
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.

+2 is the charge represented Cu2+
In oxygen, each atom gains two electrons to achieve a stable electron configuration through forming two covalent bonds. This means that each oxygen atom gains two electrons to reach a full valence shell.
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.
