(a) the same physical properties
(b) different chemical properties
(c) different number of neutrons
(d) different atomic numbers.​

Answer 1

Answer:

The correct answer is option c

Answer 2

Answer:

(c) different number of neutrons

explanation :

Isotopes are different species of an element with different mass. And the mass of an atom depends on the number of protons and neutrons. since, isotope is a type of species of an element, the atomic number (ie the number of protons) does not change. Therefore, the number of neutrons change.
