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
An atom's atomic number tells us the number of protons it has in its nucleus. Checking a Periodic Table, we see that selenium/'s atomic number is 34. Thus, there are 34 protons in the nucleus of a selenium atom.
there are 34 protons 43 neutrons in selenium
Selenium has 34 protons, 34 electrons. the number of neutrons depends on the isotope. Se-79 isotope has 45 neutrons (79 - 34 = 45)
34 protons 43 neutrons in selenium
Selenium has 34 electrons.

The three constituents that make an atom are protons, neutrons, and electrons.
In the atom are: neutrons, protons, electrons.
Boron is an atom or element, and it contains protons, electrons, and neutrons.
The structure of an atom, it has electrons, protons and neutrons. The electrons circle around the middle of the atom and the middle of the atom is made up of protons and neutrons.
