Question

why can a carbon atom can form a variety of compounds?
it has 2 valence electrons that allows it to bond with up to 6 other atoms.
it has 12 valence electrons that allows it to bond with up to 4 other atoms.
it has 4 valence electrons that allows it to bond with up to 4 other atoms.
it has 6 valence electrons that allows it to bond with up to 6 other atoms.

Explanation:

Carbon is in group 14 of the periodic table. The number of valence electrons for group 14 elements is \(4\). Each valence electron can participate in a bond. So, a carbon atom with \(4\) valence electrons can form bonds with up to \(4\) other atoms (through single, double, or triple bonds), which is the basis for the variety of carbon - containing compounds.

Answer:

It has 4 valence electrons that allows it to bond with up to 4 other atoms.
