Question

The two members of group 14 in the periodic table are carbon and silicon
(a)write electronic configuration of both elements
(b)deduce their valencies
(c)name the element which is electonegative answer with proper reason
(d)find out whether these elements are metal or non- metal?

Answer 1

Carbon 1s²2s²2p²
Silicon 1s²2s²2p63s²3p²
both have velency equal to 4
Electronegativity increases as we move from. down to up in a group so carbon is more electronegative
Carbon is metal while silicon is semiconductor
