Would anyone like to share their mnemonic devices for general chemistry?

Question

for example, ways to remember types of bonding, or steps in balancing redox reactions ... anything of the sort. I made up a looong song to remember the basic polyatomic ions, anything that would stick in my brain would be greatly appreciated!

Answer 1

sulfate and sulfite.

sulfate = Too late for the sofas.
Too late = 2 negative, for (4) and SOfas.
"late" ends in ATE

sulfite = So, threesome tonight?
tonight = 2 negative
threesome is the 3 after the SO
"tonight" ends in the sound ITE

I just made these up.
