phosphorus forms P4O6, and P4O10. In the forst it forms 3 bonds to oxygen (single bonds) and in the latter 5 3 single and one double. there are a few other obscure oxides whose molecules contain "mixtures" of 3 and five bonded P.
double covalent bonds
Phosphorus is a nonmetallic element so phosphorus-phosphorus bonds are covalent.
The difference of electronegativity between hydrogen and phosphorus is not adequate to form ionic bonds.

Carbon makes four bonds with oxygen in carbon dioxide.
double covalent bonds
Valence is the number of bonds to other atoms. It is not always numerically equal to the oxidation number.The valence of phosphorus in PCl3 is 3; of P in PCl5 is 5; of P in H3PO4 is 5 (one of the bonds to oxygen is P=O).
mostly all nonmetals such as oxygen, sulfur, chlorine, bromine, fluorine, iodine, phosphorus, etc

8,75 moles of oxygen are needed.

what is the formula for phosphorus trichloride
The bond between phosphorus and oxygen are actually covalent. Eventhough those bonds are also with slight ionic characters. It violently reacts with water to form phosphoric acid.
it becomes phosphorus oxide
