Magnesium has two electrons on its outer shell Each of the electrons will be shared with a Florine atom. This results in a compound # MgF_2#

Each Florine starts with seven electrons around the atom, combining with the Magnesium atom give the Florine eight electrons around each Florine atom. This eight electrons are found in four pairs. shown in the diagram as a pair on top a pair on the left a pair on the bottom and a pair on the left.
