@Felthry hol up.
those are the elements, with their chemical symbols. arranged like the periodic table of the elements...
but that's clearly an excel document
and I'm not sure what the (IO4)3 things are.
...
something to do with periodics or something? in an excel table?
@Felthry that's....
really clever. really obtuse, but also very clever XD
@Nine the IO₄ anion is referred to as periodate (pronounced like per-iodate, like iodine not period), and the adjective form is periodic
It's an excel table because I couldn't be bothered to type it up in any other format
