Neutrons-About 99
18 protons 18 electrons 22 neutrons
41 protons 41 electrons 52 neutrons
55 protons and electrons and 78 neutrons
Protons: 73 Neutrons: 108 Electrons: 73
Neutrons - 118 Protons/electrons - 79
18 protons 18 electrons 22 neutrons
The formula is Atomic Mass (rounded to the nearest whole number) minus the Atomic Number. This works because Protons and Neutrons have virtually the same mass, and electrons virtually none. As well as the Atomic Number being equal to the amount of Protons. Essentially: Protons + Neutrons - Protons = Neutrons. Basic Prealgebra. So to find the amount of Neutrons in Erbium: Erbium's Atomic Mass rounded (167) - Erbium's Atomic Number (68) = approx. 99 Neutrons
