Question

The two carbon atoms represented below are isotopes:

The atoms of both isotopes have six protons.

Give one other way in which the isotopes are similar.

Answer 1

1. Isotopes are atoms having same number of protons and electrons, but different number of neutrons.
2. Isotopes Carbon (${}_6{}^{12}\mathrm{C}$),$\left({}_6{}^{13}\mathrm{C}\right),\left({}_6{}^{14}\mathrm{C}\right)$ have same number of electrons as protons in them.
3. Each isotope of carbon has $6$ protons so it will also have $6$ electrons.
4. Hence, it's similar in the way of having the same atomic number.
