Dinitrogen tetroxide
No. Thyroxine is also called as tetraiodothyronine. So thyroxine has four iodine atoms and triiodothyronine has three iodine atoms.
Four carbon atoms and nine hydrogen atoms combine to form the compound butyl or one of its isomers.

No. Thyroxine is also called as tetraiodothyronine. So thyroxine has four iodine atoms and triiodothyronine has three iodine atoms.
Phosphate group
A double bond
A phosphorus atom surrounded by and chemically bonded to each of four oxygen atoms is commonly called a "phosphate ion" if it is a triply charged anion or a "phosphate group" if present in a covalently bonded compound.
A compound with one zinc atom, four calcium atoms, four hydrogen atoms, and six ogyen atoms.
Four carbon atoms and nine hydrogen atoms combine to form the compound butyl or one of its isomers.
It doesn't necessarily "bonds to four other atoms."
