True, False, or Sometimes true

1)A bond in which one atom contributes both bonding electron is called a polyatomic covalent bond.(True)

I think this is false. The bond in which one atom contributes both bonding electrons is called a coordinate covalent bond.

2)Carbon forms four single covalent bonds with other atoms. (Fales)

Carbon DOES form four single covalent bonds with MOST other atoms but there are instances in which it forms double bonds (with itself, oxygen, etc) and it forms triple bonds with itself. So I don't know if this statement is true or not. You be the judge of that.
