Question

2 a C In which substance is each carbon atom covalently A carbon dioxide B diamond 0 0 С graphite D methane 16. How many electrons are shared in the covale​

Answer 1

Explanation:

In the diagram some carbon atoms only seem to be forming two bonds (or even one bond), but that's not really the case. We are only showing a small bit of the whole structure. This is a giant covalent structure - it continues on and on in three dimensions. It is not a molecule, because the number of atoms joined up in a real diamond is completely variable - depending on the size of the crystal.
