Explanation:

If you are given atoms you need to divide by Avogadro's number 6.022x10^23

If there are 36 Strontium and 24 Phosphate, Why are there not equal numbers of cations and anions?
nalin [4]

An ion is an atom or group of atoms in which the number of electrons is not equal to the number of protons, giving it a net positive or negative electrical charge.
Due to this, anoin which is a negatively charged and is attracted to the anode (positive electrode) in electrolysis. and is considered as a proton. however Cations are positively charged and are attracted to cation ( negative electrode). its know as a electron .

So, the net positive or negative electrical charge explains the difference in the amounts of phosphate and strontium.

An ion can never have the same amount of anions and cations.
