Hafnium, a lustrous, silvery transition metal, comprises 72 protons, 106 neutrons, and 72 electrons.
Hafnium protons
- Protons = atomic number
From the periodic table, find the atomic number of hafnium.
The atomic number of hafnium is 72. Hence, hafnium has a total of 72 protons.
Hafnium neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of hafnium is 178.49, so we’ll take the roundup value as 178. And the atomic number of hafnium is 72.
Subtract the atomic number (72) from the atomic mass (178). Hence, hafnium has a total of 178 – 72 = 106 neutrons.
Hafnium electrons
- Electrons = atomic number
The atomic number of hafnium is 72. Hence, hafnium has a total of 72 electrons.
