Hi there.
00:02
In this question, we are trying to name k2so4.
00:09
Well, we see that this is ionic, and we know that because potassium is a metal, and metals will lose electrons to form cations.
00:28
So4 is an anion.
00:30
It's the polyatomic anion sulfate.
00:35
So, ionic compounds are composed of a cation and an anion.
00:39
When we write their names, we write the cations name first, followed by the anions name.
00:54
Alright, it's important to note that potassium is found in group 1 of the periodic table.
01:00
Atoms in group 1 of the periodic table, when they form ions, they always form ions with a single positive charge.
01:07
They do not have what is called varying oxidation states...
