Therefore, the formula is Mg+F2--->MgF2. The greater the difference in electronegativity, the greater the ionic character of the bond between them. Compounds of two elements are usually ionic when one element is a metal and the other is nonmetal. Magnesium is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure. 26.0 grams of magnesium nitride are reacted with 17.6 grams of water.
