Question

If the atomic number of Chlorine atom is 17 and atomic mass is 35.5u, compute the number of protons, electrons and neutrons.

Answer 1

Answer:

Protons= 17, Electrons= 17, Neutrons= 18

Explanation:

The atomic number (Z) corresponds to the number of electrons that is equal to the number of protons (17). The mass number (A) corresponds to the sum of protons and neutrons present in the nucleus (35). Therefore, we calculate the number of neutrons: 35-17 = 18
