I don't know Se-50.
Neutrons = Mass number (Se-80) minus Atom (or proton 34Se) number (34) = 80-34 = 46 neutrons
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
The isotope, Se-79, has 45 neutrons (79 - 34 = 45)
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
The nucleus of selenium has 34 protons. The number of neutrons depends on the isotope and can vary from 31 in Se-65 to 60 in Se-94 isotope.
How many neutrons would it have if it had 11 neutrons? 11.
There is no neutrons in Hitrogen.
18 neutrons
It has 20 neutrons.
117 neutrons.
61 neutrons 47 protons and 47 neutrons
