There is a mnemonic, sort of, which I have seen but I don't remember it. Give me a few minutes.

I don't remember the mnemonic; however, look at your periodic table. H is the first element and you must remember to start with that one, then all of the others are bunched. Look at N, O, F are on a straight line from left to right and when you get to the F, you simply go down the table from F to Cl to Br to I. P and S just add another row (1 below N and 1 below O). My periodic table has them colored red for agases and blue for liquid and black for solid. Br is a liquid and I is a solid. Of course P and S are solids.
