when compared to the mass of protons and neutrons, the mass of the electrons is negligible and hence not included in atomic mass.

Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?
electron
What is negatively charged particles of atoms with almost no mass called?
An Electron
Why an electron is ignored from the calculations of the weight of an atom?
The mass of a proton is about 1.67 * 10−27 kg or 1.007 atomic mass units. Neutrons are very close to this, at 1.675 *10-27 kg, or 1.009 atomic mass units. Electrons have a mass less than approximately 1/1836 of this so can effectively be ignored.
What does the atomic mass of an electron represent?
The mass of an electron is atomic mass units is 5,485 799 090 70(16); the mass of the electron is not an atomic mass.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
Which particle has the smallest mass atoms or electron?
An electron has a much smaller mass than any atom.
Which component of an atom does not add to the atoms mass?
electron
Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?

Is the Mass of hydrogen atom is about the same as a proton?
Yes, in general. All hydrogen atoms contain one proton, most with no neutrons and all neutral atoms with one electron - and the electron has a much smaller mass. Some hydrogen atoms contain one (or, rarely, two) neutrons and so are heavier. But on average the atom has a mass much the same as a proton.
What the smallest particle in a atom?
Size on the scale of atoms is very hard to define. The electron has zero mass. Quarks have varying amounts of mass.
How does Relativity explain an electron's mass seeing that an electron doesn't take up any space?
its because i really dont know
Explain how copper atoms are converted into copper plus ions in a mass spectrometer?
An electron beam is shot at the Cu atoms, from an electron gun, this knocks out electrons meaning the overall charge of the atom becomes positive as negative electrons have been lost.
How does the mass of a proton compare to a neutron?
Yes, in general. All hydrogen atoms contain one proton, most with no neutrons and all neutral atoms with one electron - and the electron has a much smaller mass. Some hydrogen atoms contain one (or, rarely, two) neutrons and so are heavier. But on average the atom has a mass much the same as a proton.

What mass of sodium metals contains the same number of atoms as 12.00g of carbon?
i dont know the answer
