Nuclear Physicists don't really count electrons to have weight. An atom's mass comes from protons and neutrons.
you can find electrons by subtract the atomic number and atomic mass.
The mass number doesn't depends on the number of electrons.
Mass number..can be calculated..by the sum of No. of protons and the No. of electrons. And this would give you the the mass number of the element.
By the addition of the number of protons and the number of electrons
Well, honey, to find the protons, electrons, and neutrons for strontium with a mass of 83, you need to look at the periodic table. Strontium has an atomic number of 38, which means it has 38 protons and 38 electrons. To find the number of neutrons, you subtract the atomic number from the mass number, so for strontium-83, you have 45 neutrons. Voila!
It depends on the atom you are reffering to, but to find the electrons take away the number of protons from the mass number of the atom.
An element's atomic mass does not include the mass of its electrons. Electrons have such a small mass compared to protons and neutrons that they are not typically included in calculations of atomic mass.
because the electrons plus the nuetrons equal the mass
if it has protons, neutrons and electrons. It also has to have an atomic number and atomic mass.
no, you add the protons and neutrons
Electrons are the same thing as protons so, you would look at the first # in the square "Atomic Mass" andthere's your awnser.
