This is because the p orbitals have the same energy and the electrons would rather be in separate orbitals. The actual location of electrons in a carbon atom cannot be determined with certainty and the electrons appear to be 'smeared' into orbitals as shown below. Isotopes are atoms which have the same atomic number but different mass numbers. They have the same number of protons but different numbers of neutrons.
The number of neutrons in an atom can vary within small limits. For example, there are three kinds of carbon atom 12C, 13C and 14C. They all have the same number of protons, but the number of neutrons varies. These different types of carbon atoms are called isotopes. The fact that they have varying numbers of neutrons makes no difference to the chemical reactions of the carbon atom.
