What is the calculation of ion charge?

Ion Charge = Number of protons-Number of Electrons

Describe a positive ion!

-it has more protons than electrons

-They are often called cations

How are positive ions generated?

By removing an electron.

Describe Negative ions!

-It has lesser ions protons then electrons

-They are often called anions

What is the overall charge of any substance?

Zero

What are isotopes?
