How many valence electrons does carbon have?

and carbon atoms always have how many covalent bonds?

Answer:
4
4 valance electrons,
4 convalent bonds
4 and 4
It always has 4 covalent bonds. To be full it needs 8 electrons. It only has 4 thus needing 4 more to be full; it bonds with another atom who needs to either gain or give up 4 bonds to either be full or at least close to it.
4

the number of valence electrons from an atom in the main group is the same as its group number.

Carbon will have 4 bonds. 4 bonds means that carbon will be surrounded by 8 total electrons (2 in each bond) which means C has an octet and C always follows the octet rule
