4 because it is very amazing
Ethane (CH3—CH3) is an example of a compound having a single bond between 2 carbon atoms. Each carbon atom in ethane forms 4 bonds: 1 to a carbon atom and 3 to each of the attached hydrogen atoms. A single covalent bond containing 2 shared electrons is also called a sigma (σ) bond.
4 because it is in an excited state. Has 4 unpaired electrons.
A carbon atom is capable of holding up to four bonds, such as the molecular structure of diamond which is a 3D latice structure made up of very strong covalently bonded carbon atoms.
Three. :)
