write the formula for the ion formed when each of the following loses its valence electronsaaluminumblithiumcbariumd.pottasiume.calciumfstrontium
Losing valence electrons means ending up with the same number of electrons as a noble gasJust find each of the elements in the periodic table, then count the boxes backwards until you reach a noble gasThe number of boxes it is away from a noble gas is the number of positive charge it will have when it loses its valence electrons.
