Selenium
50.69% natural abundance
Selenium (Se) has an atomic weight of 79,04.
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
Selenium with an atomic mass of 80 has 46 neutrons.
Selenium (Se) is in oxygen family (group 16 or VIA) and in 4th period.
