      44) comes fro m the Group I element. Similarly to compound B, the sulfate io n is a -2 charge and Group I metals form ions wi th a +1 charge, thellowsn it fo that the fo rmula o f C is M 2 SO 4. So the relative atomic mass of the metal in compound B is 44 2 = 22. This matches closely to sodium which is 23, hence compound C is Na 2 SO 4.

      Group numbers can help you determine the number of valence electrons: Group 1 has 1 valence electron. Group 2 has 2 valence electrons. Groups 3–12 are transition metals and have 1 or 2 valence electrons. Groups 13–18 have 10 fewer than the group number. For example: Group 13 has 3 valence electrons.
