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.
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
because the electrons plus the nuetrons equal the mass
To find the total mass of an atom, you sum the masses of its protons, neutrons, and electrons. Although electrons contribute very little to the overall mass, the combined mass of protons and neutrons, which are located in the nucleus, accounts for most of the atom's mass. The atomic mass can be found on the periodic table, typically expressed in atomic mass units (amu), which reflects the average mass of the atom's isotopes. For a more precise calculation, you can use the actual masses of protons (approximately 1.007 amu) and neutrons (approximately 1.008 amu) along with the negligible mass of electrons (approximately 0.0005 amu).
Electrons are the same thing as protons so, you would look at the first # in the square "Atomic Mass" andthere's your awnser.
