Question
Element 'M' forms a chloride with the formula MCI2, which is solid with high melting point. To which group of the Periodic Table does the element 'M' belong?
✓

Answer

The valency of chlorine is 1. Therefore, if the element M is forming a chloride of the formula MCl2, it means that the valency of M is 2. Also, since the compound MCl2 has high melting point, it means that it is an ionic compound. Hence M is a metal and belongs to group 2 of the periodic table.
