Magnesium has three electron shells. The electron configuration is 2,8,2
Magnesium has 3 electron shells.
2
Magnesium has 2 electrons in its outermost electron shell. As a result, you would expect magnesium to form ions with a charge of +2 by losing these two outer electrons to achieve a stable electron configuration.

Magnesium has three electron shells. The electron configuration is 2,8,2
Magnesium has 3 electron rings.
Magnesium has 3 electron shells.

Actinium has seven electron shells.
Copper has four electron shells.
Gallium has three electron rings or orbits, based on its electron configuration of [Ar] 3d10 4s2 4p1.
The shorthand electron configuration of magnesium is [Ne]3s2.
Actinium has seven electron shells.
The sub-atomic particle that orbits the nucleus in an atom is called an electron.
The first electron affinity of magnesium is exothermic. This means that energy is released when a neutral magnesium atom gains an electron to form a magnesium ion.
2 Because Magnesium only has 2 electrons in it's outer shell
