Potassium(K) + Iodine(I) = PotassiumIodide(KI)
BUT I am asked to explain and illustrate using a diagram.
Normally, when i use the method that i understand(valency), i get KзI instead of KI. I need explanation. Help!!

I drew a diagram for you. Click link below.
You have to remember that K and I will form an ionic bond, and your teacher wants you to show that one electron from K will be given to I. When K loses an e-, it will become K+ and when I gains an e-, It will become I-. This positive and negative charge attracts the cation and anion to from an ionic bond.

Where does K3I come from? What are your reacatants? the valancies balance one another out; potassium ion= K+ and iodine ion= I-.....you just need to make good use of the resource suggested.

I'm dumb in chem, but just read that KI is an ionic salt and it is K+ cation attracted to I- anion. Whatever that means. Ionic bond, not covalent, I guess.

It is already balanced.
Potassium (K) is a Group I element, meaning it has ONE electron on it's outermost shell.
Iodine (I) is a Group VII element, meaning it has SEVEN electrons on it's outermost shell.
Thus, combining them together, you shall get Potassium Iodide (KI) as it takes EIGHT electrons to balance a compound.
