Question

Isotopes have identical chemical behaviour because:

पर्याय

• They have the same number of neutrons

• They have the same mass

• Their electronic structure is the same

• They have the same nuclear volume

Answer 1

Isotopes have the same number of protons but a different number of neutrons. Since the number of protons (atomic number Z) determines the electronic structure, isotopes have identical chemical behaviour because their electronic structure is the same.
