Neutrons = Mass number (Se-80) minus Atom (or proton 34Se) number (34) = 80-34 = 46 neutrons
since there are 22 protons there has to be 22 nuetrons since there are 22 protons there has to be 22 nuetrons
There are stable isotopes of four elements with 48 neutrons: selenium-82, krypton-84, rubidium-85, and strontium-86.
there are 12 nuetrons in an atom of magnesium
im eleven and i know the answer the answer is 18 nuetrons
protons and nuetrons are equal to no. of electrons present in atom
26 nuetrons, 22 electrons, and 22 protons
