Number of neutrons- 40-20 =20, electrons-20 and proton -20.
The mass number of an isotope is the sum of the number of protons as well as neutrons in the atomic nucleus.
Overall, the atomic number is the number of protons.
Even the calcium-40 isotope has a mass number of 40 as well as an atomic number of 20, therefore it has 20 protons
