Since Selenium has an atomic number of 34, it has 34 protons and electrons at its elemental resting state. The most common isotopes have 44 and 46 neutrons, which you get from subtracting the atomic number from the Atomic Mass.
There are 18, 20 or 22 neutrons.
Hydrogen typically has 0 neutrons.
In-115 isotope has 66 neutrons
the average amount of neutrons in chlorine is 18, but there could be more or less with the different isotopes
Number of neutrons is 48 (mass number) minus 21 (proton number) = 27 (neutron number)
34
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.
18 neutrons
117 neutrons.
There is no neutrons in Hitrogen.
It has 20 neutrons.
