Arsenic has 33 protons, 42 neutrons, and 33 electrons.
Arsenic protons
- Protons = atomic number
From the periodic table, find the atomic number of arsenic.
The atomic number of arsenic is 33. Hence, arsenic has a total of 33 protons.
Arsenic neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of arsenic is 74.9216, so we’ll take the roundup value as 75. And the atomic number of arsenic is 33.
Subtract the atomic number (33) from the atomic mass (75). Hence, arsenic has a total of 75 – 33 = 42 neutrons.
Arsenic electrons
- Electrons = atomic number
The atomic number of arsenic is 33. Hence, arsenic has a total of 33 electrons.
