It is, without question, a tetrahedral model with the following possibilities:

Methane
Phosphate
Ammonium


EDIT TO ADD

Just saw the double bond.....it's phosphate!

It is intended to be phosphate. Strictly speaking, it is phosphoric acid PO(OH)3, without the hydrogens showing, which actually looks a little different than PO4--- since in phosphate, all of the oxygen atoms are equivalent, while in phosphoric acid, one is double bonded and three are single bonded to the central P.

The reason I picked phosphate is that in the real world, phosphate binding has been my most substantial accomplishment, using a polymer that binds it in people who suffer from hyperphosphatemia. For a while, sevelamer was the largest volume (mass sold per year) brand name pharmaceutical in the world. It went generic a bit ago, but peaked at sales well over $1 billion per year.

MolyMod molecular models sets use purple for the phosphorus nucleus.​

Phosphorus burns a pale bluish green when combusted, but I wonder if anyone has seen a molecule up close to see what it actually looks like? Heisenberg may have, according to my records but that cannot be verified using Google. He was cancelled for his views.​
