## Does calcium have 20 neutrons?

In your case, you know that an atom of calcium, Ca , has 20 neutrons in its nucleus. This means that in order to get its mass number, all you need to know is how many protons are found in its nucleus. As you know, the number of protons an atom contains in its nucleus is given by that atom’s atomic number.
