Answer:

BERYLLIU :- Be (Z = 4). Its inner shell electrons are 2 and outer shell electrons

are 2. We can represent its Lewis notation as \ddot { Be }.

CALCIUM :- Ca (Z = 20). It has {{2e}^{-}} in Ist shell, {{8e}^{-}} in IInd shell and {{10e}^{-}} in IIIrd shell. So, we can represent its the electronic configuration of Ca is 2, 8, 8, 2. So its Lewis notation-is _{ . }^{ . }{ Ca }
