In the Lewis structures listed below, M and X represent various elements in period 3 of the periodic table. Write the formula of each compound using the chemical symbols of each element: 3+ MX: Solution a) The first compound formed will be MX [since the cation is present in +2 oxidation astate and anion is present in -2 oxidation state] The compound will be MgS b) The second compound formed will be MX3 [since the cation is present in +3 oxidation astate and anion is present in -1 oxidation state] The compound will be AlCl3 c) The third compound formed will be M2X [since the cation is present in +1 oxidation astate and anion is present in -2 oxidation state] The compound will be Na2S .
