Question

The isotopes of an element contain (a) same number of neutrons but different number of protons
(b) same number of neutrons but different number of electrons
(c) different number of protons as well as different number of neutrons
(d) different number of neutrons but same number of protons

Answer 1

Answer:

The isotopes of an element contain: (d) different no. of neutron but same number of protons.

Answer 2

Answer is Option (d)

Explanation:

• Isotopes of any element that variate in the number of Neutrons but not in Protons (nucleon) number.

or

• The elements having the same number of Protons but different number of neutrons comes under the category of Isotopes.

• Isotopes have been found mostly naturally.  

So, we can grade them in the category of elements with same electrons & protons but different neutron number.
