Vedclass · Answer

(A) The two atoms are isotopes of the same element because they have the same atomic number $(Z = 6)$ but different mass numbers ($A = 12$ and $A = 13$).For the atom with mass number $12$: Number of protons $(p)$ = $6$,number of electrons $(e)$ = $6$,and number of neutrons $(n)$ = $12 - 6 = 6$.For the atom with mass number $13$: Number of protons $(p)$ = $6$,number of electrons $(e)$ = $6$,and number of neutrons $(n)$ = $13 - 6 = 7$.Therefore,the atom with atomic weight $13$ contains one more neutron than the atom with atomic weight $12$.

Compared with an atom of atomic weight $12$ and atomic number $6$,the atom of atomic weight $13$ and atomic number $6$:
