Sagot :
The number of electron energy levels in a magnesium atom is: 3
What is electron energy level?
The set distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells). Higher energy electrons have greater energy as you move out from the nucleus. A region of space inside an energy level known as an orbital is where an electron is most likely to be located.
An electron rotating in a shell is connected with a particular amount of energy. When it moves from one energy level to another, or when it leaps to another shell, the energy changes. As a result, a shell also indicates an electron's energy along with its position, and these are known as energy levels.
The distribution of electrons in the electron shells for the magnesium atom is given as : 2,8,2.
So, the total number of energy levels are 3.
