Explain the interaction between two charged metal objects and a change in the electric field.
(I really need help fast!!)

Explanation:

Ions are formed when an atom of an element that lacks stable configuration or octet configuration, looses or gains electrons to attain stability.

Magnesium atom contains 12 electrons, with an electron configuration of 2:8:2. Therefore, it requires to loose two electrons to attain stability, thus forming an ion. During ion formation, the number of protons and neutrons are not affected thus they do not change.

Therefore; Magnesium atom contain 12 electrons, 12 protons and 12 Neutrons. While magnesium atom contains 12 protons, 10 electrons, and 12 neutrons.
