I was working on mastering chemistry work and I can't seem to get the answer correct. I'm curious to what the structure is.
I assumed it was .. .. .. But apparently this is wrong, if someone could explain to me why this is wrong and how I can
:P-P-P: get to the solution that would be great. I know that they all have single bonds and it has 20
l electrons total. Thanks!
:P:

Woops all the :P represent a : and the element P.

There are only 4 lone pairs...

and P atoms form tetrahedron

Oh wow that was stupid... So I also did it where each of the Ps bonded singly with the 3 other Ps. Then a single lone pair on each. This was also wrong. They each have a full octet though and 20 electrons.
