Ans 4) Chlorine-35 atom and Chlorine-37 atom are called isotopes... Use these two examples to explain what is 'isotopes'.
Defination of iostopes, different atoms of the same element which have the same number of protons but different number of electrons.
Chlorine-35 have a proton and neutron no. of 35.
Chlorine-37 have a proton and neutron no. of 37.
Both have the same number of 17 protons.
Chlorine-35 has 18 neutrons (35-17=18)
Chlorine-37 has 20 neutrons (37-17=20)
Therefore, Chlorine-35 and Chlorine-37 are isotopes.
