Covalent bonding and naming

Why do compounds form covalent bonds?

• They have enough electronegativity difference to take an electron

• They already have a satisfied octet

• They have a medium to low difference in electronegativity and share electrons

• They need to get rid of their valence electrons

How many covalent bonds will Carbon commonly form to fill its octet?

• One bond

• Two bonds

• Three bonds

• Four bonds
