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 no electrons bound in the nucleus. The electrons form a cloud around the nucleus on the average of several hundred nuclear radii away. Occasionally an electron may dip down inside a nucleus and get captured if there is a deficiency of neutrons. This is called electron capture and results in a change of element to Z-1. Selenium-73 (Z=34, N=39) does this and changes to As-73, which is also radioactive by electron capture.
The element symbol Se represents selenium. The most common isotope of selenium is selenium-80, which has 45 neutrons.

Argon has 22 neutrons.
Indium 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)
Bi-211 (and all other Bi isotopes) has atom number 83, hence there are 83 protons.

Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
I don't know Se-50.
Neutrons = Mass number (Se-80) minus Atom (or proton 34Se) number (34) = 80-34 = 46 neutrons
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
Palladium has 60 neutrons. It has an atomic number of 46, which means it has 46 protons. To find the number of neutrons, you subtract the atomic number (protons) from the atomic mass (protons + neutrons). Palladium's atomic mass is approximately 106.4, so 106.4 - 46 = 60 neutrons.
There is no neutrons in Hitrogen.
117 neutrons.
