Question

Calculatenumber of Proton, Neutrons
and electrons in the
following :-

32
X
15
32
X
17
​

Answer 1

Explanation:

Atomic number=No. of protons=No. of electrons in ground state(unchanged atom)

Atomic number=13=No. of protons

Atomic 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
