1.	State the characteristics which remain similar and those which show a transition on moving down a subgroup.
Answer» Characteristics which remain similar on moving down a group/ sub-group are: 1. Valency of electrons. 2. Chemical properties. Characteristics which show a transition or moving down a group are: 1. Metallic character increases down the group. 2. Number of electron shells increases down the group. 3. Atomic size increases down the group. 4. Ionisation potential decreases down the group. 5. Electron affinity decreases down the group
