What is the chemical formula for 2 Fluorine, 1 Chlorine, 1 Phosphorous?

Question

Its an online quiz question and I only have 2 answers left.

I thought it would be P1Cl1F2 but its not.

Speed helps so first to get it right probably get BA... lol just realized Best Answer abbreviated is BA... awesome.

Oh, and thanks.

Answer 1

Well, when you only have one atom in a compound you don't write the "1".

So it would be PClF2.

Answer 2

Well, your answer is correct, but do not need to ones (chemical formulas assume that no number is one).

So you will write:

PClF2

good luck.
