Diamond is a covalently-bonded substance made of pure carbon. Each carbon atom has six total electrons so this means carbon shares ________ electron(s) with other carbon atoms.
A. one
B. two
C. four
D. six
when two carbon atoms are covalently bonded together, they try to achieve an octet structure so their electrons are 4 in number while each of them donates their remaining 2 so they end up sharing 4.
