Mass number is defined as the number of protons and neutrons. It is related to Atomic Mass which incudes electron mass and nuclear binding energy , (binding energy reduces the overall mass relative to the combined masses of the protons and neutrons.) Electron mass is not included as mass number is element specific wheras the count of electrons varies depending on the chemical state.
The mass of electrons is negligible compared to the mass of the protons and neutrons, binding energy is a larger effect.
What else can I help you with?
Why don't he include the electron in atoms mass?
when compared to the mass of protons and neutrons, the mass of the electrons is negligible and hence not included in atomic mass.
What does Bohrs diagram represent?
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
How you can use the atoms mass number and atomic number to determine the number of protons electrons and neutrons in the atom?
The numbers of protons and of electrons in an atom are both the same as the atomic number, and the difference between the mass number and the atomic number is the number of neutrons in the atom.
How to find the number of protons atomic number and the mass number with 12 as the number of electrons and 10 as the number of neutrons?
To find the number of protons (atomic number), you can use the number of electrons, in this case 12 electrons. Since atoms are electrically neutral, the number of protons is equal to the number of electrons, which is 12. To find the mass number, you add the number of protons and neutrons together. In this case, you have 12 protons and 10 neutrons, so the mass number would be 22.
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number

Atomic mass is number of protons added to the number of neutrons. Why is number of electrons not included in it?
Because electrons are very light particles and do not effect the mass, if proton and neutrons are elephant then electrons are ants , how ants effect the mass and weight of elephant ?
Which subatomic particles have mass and re included in the calculation of the atomic mass number?
Protons and neutrons are the subatomic particles that have mass and are included in the calculation of the atomic mass number. Electrons have very low mass compared to protons and neutrons and are usually not included in the atomic mass calculation as they contribute very little to the overall mass of an atom.
How do you find the mass number of an atoms?
Can't you check the periodic table dumbo anyways just add up the protons and electrons to get mass number.
When calculating an atoms approximate mass how is the mass of electrons figured?
electrons are the same as protons

How many protons electrons and neutrons does 31potassium have?
From the periodic table, potassium has an atomic number of 19. This means that potassium atoms have 19 protons in their nuclei. In a neutral atom, the number of protons equals the number of electrons. Therefore, potassium atoms have 19 electrons. Mass number is the sum of protons and neutrons in the nucleus of an isotope. If you know the mass number and number of protons, subtract the number of protons from the mass number. In the case of potassium-31, the mass number is 31. So, subtract 19 from 31 and you get 12, which is the number of neutrons. So the atoms of potassium-31 has 19 protons, 19 neutrons, and 12 neutrons.
What determines an atoms atomic mass?
It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
