1.	Consider three elements with atomic no. 4, 12,20 respectively. 1 Mention their position in the periodic table (2) which one is most metallic in character? 3 )which one is least reducing in character?
Answer» tion:atomic no. 4 = Berylliumperiod = 2 group = 2 atomic no. 12 = Magnesiumperiod = 3group = 2 atomic no. 20 = Calcium period = 4 group = 2AS down the group metallic character INCREASES. So, calcium is most metallic As down the group REDUCING power increases. So Be has least reducing power.
