Zirconium has 40 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a zirconium isotope = Mass number - 40
The mass number of zirconium 98 is 98. This number represents the total number of protons and neutrons in the nucleus of an atom of zirconium. Zirconium has 40 protons, so the remaining 58 particles are neutrons.
The most common isotope of selenium is selenium-80, which makes up about 50% of naturally occurring selenium.
40 protons and 40 electrons.The most stable isotope of zirconium (Zr-91) has 51 protons.
