- 5What is the definition of mass number?The total number of protons and neutrons in the atom.
- 6What are isotopes?These are atoms with the same number of protons but different number of neutrons.
- 7Why do isotopes have similar chemical properties?This is because the electronic configuration is still the same. the only difference is that their physical properties are going to be different because they have different masses.
