because the electrons plus the nuetrons equal the mass
depends on the electrons
Yes, electrons have a mass of 9.1094 X 10−31 kg.
electrons are the same as protons
If you know the mass of one mole of those atoms (the mass number listed on the periodic table), then you divide that number by Avogadro's constant: 6.022x10^23 which gives you the mass of one single atom
They are different because of the number of electrons in there electron cloud. True, the number of electrons are specific to the type of atom but so are the number of protons. The atomic number of the atom is directly related to the number of protons and electrons it has. So carbon for example is given the atomic number 6. Thus it has 6 protons and 6 electrons. It's atomic mass is 12.0107 amu. This we can round to 12. To aquire the atomic mass of a given element you add the number of protons and nuetrons together since the electrons are so infinitely small they are not considered to have any mass. We know from the atomic number that carbon has 6 protons, it's atomic mass is 12, so that means the number of nuetrons must also be 6. This doesn't exactly answer the question though. The obvious things that differentiate one atom from another are their atomic number, the number of protons and electrons inside an atom, and their atomic mass.

For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
The mass number is the amount of neutrons within the nucleus minus the amount of protons/electrons.
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
Actually, electrons do have mass.
strength = molar mass = number of electrons
its Atomic Mass.
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.
...electrons, as they account for a negligible mass relative to the atom as a whole (electrons make up 1/1840th of the total mass, to be precise).
