For example carbon has three naturally occuring isotopes called carbon 12, carbon, 13, and carbon 14 (the 12,13,14 are the mass numbers) they are all carbon atoms because they contain 6 protons and have the atomic number of 6 but a different mass number. Carbon 12 and carbon 13 are stable isotopes of carbon but carbon 14 is unstable and therefore radioactive when an element undergoes radioactive decay the rearrangements of protons and neutrons can cause the nuclei to emit high-energy
Basically, the answer for this would be N or NITROGEN. If we combine nitrogen with chlorine, what happens is that, it can attract more chlorine electrons towards itself. The reason is that, nitrogen is considered more electronegative compared to chlorine. So best answer for this is the first option.

Explanation:
The IUPAC system of nomenclature enables the structure of molecules to be written seamlessly from the name of the compound. Hence it is commonly called the systematic nomenclature.
The parent chain here is propane. It is substituted at the 2- position by a methyl group and at the 3-position by 4-chlorophenyl group as we can see in the image attached to this answer.
