Question

Be, Mg, Ca, Sr, Ba are group 2 metals. which of these will form ions most readily and why?

Answer 1

Barium will make the ions most readily because of the larger size of the Ba. As we move down the group, the size of the atom increases due to which the bonding is not strong. Metallic character increases which indicates the ease with which an element lose its electrons to form ions. Thus, Ba will form ions most readily.
