How many potassium ions are needed to balance the charge of one sulfide ion

two (2)

Explanation:

Potassium is one of the alkali metals represented by the symbol K. It belongs to group 1A of the periodic table and has a charge of +1.

Sulphide is a negatively charged ion of element sulphur. It is represented as as it has 2 negative charges.

In order to balance, we need equal number of positive and negative charges.

Negative charge = -2

Positive charge = +1

Therefore, we need 2 positive charges and hence 2 Potassium ions.

It is concluded that 2 Potassium ions are required to balance the sulphide ion.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
