Expert Solution
Step 1

To fill the table, we would use the following relationships : 

1.) Number of protons = atomic number of element. 

So , from number of protons we can determine the element symbol. 

2.) Mass number = number of proton + number of neutrons. 

3.) For neutral atom ( which doesn't have any charge ) , number of protons = number of electrons. 

4.) For a charged atom, 

Number of electrons = number of protons - charge . 

5.) Isotope notation is written using the symbol , atomic number and mass number .
