Answer:

the element with only one shell and the shell is complete is helium the element which complete second sale twice the element by the first cell is neon the valence is of the electrons of lithium is one because the last cell is only one electron so valency is one and neon is is zero because the second sale is it 8-8 is0 chlorine is the element which has valency 7 the symbol of oxygen is O2
