The official IUPAC name is Dinitrogen monoxide. There are two nitrogen atoms, so the prefix di- is used and there is one oxygen, so the mono- prefix is used.
However, the compound N2O is better known as nitrous oxide, commonly known as the anesthetic "laughing gas" and an oxidizer for race cars and rockets.
(*Nitrous oxide does not actually cause laughing, but rather a semi-coherent stupor.)
The prefix "tetra-" means 4, so the formula is N4O4.
The compound name for H2O is water.
The compound name for SiI4 is tetrasilane.
The name for the compound CH2CH2CH3 is propane.
The compound name for Al2O3 is aluminum oxide.
The prefix "tetra-" means 4, so the formula is N4O4.
