45
Selenium a non metal hexagonal grey element has 34 protons and electrons. The atomic structure of Selenium has 45 neutrons.
Slenium has 34 protons and 45 neutrons! :)
Selenium has an atomic number of 34, which means it has 34 protons. To find the number of neutrons in selenium-80, subtract the atomic number (34) from the isotope number (80). Therefore, selenium-80 would have 46 neutrons (80 - 34).
The mass number of an atom is the sum of its protons and neutrons. Since selenium usually has 34 neutrons, an atom of selenium with 31 neutrons would have a mass number of 34 (31 neutrons + 17 protons).
Selenium-79 is a radioisotope of selenium containing 34 protons and 45 neutrons.
45 neutrons
A simply formula is the atomic mass of selenium (rounded to the whole number) - atomic number = neutrons. So Selenium 76 has 45 neutrons.

Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
Selenium has an atomic number of 34, which means it has 34 protons. To find the number of neutrons in selenium-80, subtract the atomic number (34) from the isotope number (80). Therefore, selenium-80 would have 46 neutrons (80 - 34).

Selenium-79 is a radioisotope of selenium containing 34 protons and 45 neutrons.
Selenium (Se) has an atomic number of 34 which means in a balance atom Se will have 34 protons and 34 electrons then Se has a mass of 79 so to get the neutrons we minus the protons from the mass and we get 45 final answer: Neutrons: 45 Protons:34 Electrons: 34
I don't know Se-50.
Selenium's mass number is 79. It is the sum of the number of protons and neutrons in the nucleus of a selenium atom.
The isotope, Se-79, has 45 neutrons (79 - 34 = 45)
