Calculate the number of protons , electrons and neutrons in the following.
(a) Chloride ion `(Cl^(-))` with `Z = 17,A =35`
(b) Aluminium ions`(Al^(3+)) ` with `Z = 13 , A=27`

Explanation

To solve the problem, we will calculate the number of protons, electrons, and neutrons for both the chloride ion (Cl^(-)) and the aluminium ion (Al^(3+)).

### (a) Chloride Ion (Cl^(-))

1. **Identify the Atomic Number (Z) and Mass Number (A)**:
- Given: Z = 17, A = 35

2. **Calculate the Number of Protons**:
...
