Atomic number=No. of protons=No. of electrons in ground state(unchanged atom)Atomic number=\\\\(13\\\\)=No. of protonsAtomic mass=no. of protons+no. of neutrons=\\\\(13+14=27\\\\)For isotope no. of proton=\\\\(13\\\\)(same atomic number but different mass number are isotopes)no. of electrons=\\\\(13\\\\)no. of neutrons=\\\\(14+2=16\\\\)
