Selenium has 34 protons, 45 neutrons, and 34 electrons.
Selenium protons
- Protons = atomic number
From the periodic table, find the atomic number of selenium.
The atomic number of selenium is 34. Hence, selenium has a total of 34 protons.
Selenium neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of selenium is 78.96, so we’ll take the roundup value as 79. And the atomic number of selenium is 34.
Subtract the atomic number (34) from the atomic mass (79). Hence, selenium has a total of 79 – 34 = 45 neutrons.
Selenium electrons
- Electrons = atomic number
The atomic number of selenium is 34. Hence, selenium has a total of 34 electrons.
