Here is a quick answere: The charge of a strontium ion is +2. The charge of an ion is determined by the amount of electrons compared to the number of protons, so a charge of +2 indicates that the ion has two more protons than electrons.
The charge on the strontium ion is +2
Definition of ion
An ion is an atom or a group of atom which possess an electric charge.
Description of ion
The charge on an ion is determined by the ability of the atom to lose or gain electron(s)
•Metals generally have positive charge since the lose electron(s) to attain stability
•Non-metals generally have negative charge since they accept or gain electron(s) to attain stability.
Description of strontium ion
Strontium, Sr is a group 2 element an as such, it will only form ion by losing it's valence electrons as shown below:
Sr —> Sr²⁺ + 2e
From the above equation, we can conclude that strontium ion, Sr²⁺ has a charge of +2
