Because carbon has 4 valence electrons

• it can form up to 4 covalent bonds

• it can form ionic bonds

• it can form only double bonds

• it can form covalent bonds with H only

Valence electrons are: 

• Electrons farthest away from the nucleus
• Electrons closest to the nucleus
• Electrons that just come and go - they don't stay with the atom
