Answer :
It has a positive charge. 22-18= +4. you just have to subtract the electrons from the protons. if you get a positive number your charge is positive if you get a negative number the charge is negative.
The charge on the ion is +4.
What is an ion?
- An ion is an atom or group of atoms where the number of electrons are not equal to the number of protons.
- To put it in a simple words, when a stable atom gains or loses an electron, it becomes an ion.
- Examples of ions are as follows: H+,Na+,Ca2+,F−,O2−
For a single atom, the charge is the number of protons minus the number of electrons.
Charge = Proton - electron
= 22 - 18
= +4
Hence, the charge on the ion is +4.
