Question
A chlorine atom whose nucleus contains 17 protons and 20 neutrons. Find out the composition of the nucleus of an isotope of chlorine?
✓

Answer

  1. 17 protons, 19 neutrons
Explanation:
Isotope nucleus means that those nucleus has same protons number but different neutrons and mass number. Since chlorine has 17 protons so its isotope also will have 17 protons.
