There is one electron in every hydrogen atom. They have 1, 2 and 3 neutrons respectively in protium, deuterium and tritium.
Electrons and Nutrons
10 protons, 8 (or more, up to 14) neutrons
none neon is the powder that electrons spark freeon to light photonic blue white
Not sure about nutrons, but xenon has between 70 and 82 neutrons.
mercury has 121 nutrons because the periodic table
Protans & nutrons
Nitrogen's atomic number is 7. Thus, it has 7 protons and 7 electrons. 14N has 14 - 7 = 7 neutrons.
Radium has 88 neutrons.
you would have to know how many protons, nutrons, and/or electrons are in the element. then you subtract the number from its mass and you get the other number. p=e=am.p+n=m.
Plutonium-239 has: 94 protons, 94 electrons, 145 neutrons.For other isotopes the number of neutrons is different.Number of neutrons = Mass number of an isotope - Atomic number of the element
Typically, 69. However it can vary by isotope.
Einsteinium typically has 99 neutrons in its nucleus.
