How is mass related to electrons?
because the electrons plus the nuetrons equal the mass
What is the mass of 3 electrons?
depends on the electrons
When calculating an atoms approximate mass how is the mass of electrons figured?
electrons are the same as protons
How do you calculate the atomic mass of an element?
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
Why does the electron cloud have a very small mass?
The electron cloud has such a small mass because that's where all the electrons are! Electrons are fundamental particles having a mass of only 9.109 X 10-31 kg. To put that into perspective, a proton has a mass of over 1,800 times that of the electron.
An element's atomic mass does not include the mass of its?
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.

Why mass of electrons is excluded from atomic mass?
The mass of electrons is not excluded from atomic mass. The mass number of an isotope of an element excludes electrons because it is the sum of protons and neutrons.From Wikipedia, "The atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units. The atomic mass is the total mass of protons, neutrons and electrons in a single atom."

When bromine reacts with other elements it gains electrons gaining electrons does not effect the mass of the bromine atoms explain why?
electrons have no mass
Why does the number of electrons have little effect on the overal mass of an atom?
Electrons are very light. Protons are approx. 1800 X the mass (rest mass to be presice). Neutrons are about the same mass a protons. So the mass of all the electrons has little effect.
What is the mass of an atom mainly determined by?
The mass of an atom is mainly determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass, while electrons have a much smaller mass.
Is it true that Unlike protons or neutrons electrons have no mass?
no electrons have mass, about 1/1800 that of a proton or neutron.
What is the mass of 5.010 18 electrons?
The mass of 5.1018 electrons is 45,546 910 75.10-13 kg.
Is the change in mass significant when an object gains or loses electrons?
No, the change in mass is generally not significant when an object gains or loses electrons because electrons have a very small mass compared to protons and neutrons in the nucleus. The change in mass from gaining or losing electrons is usually negligible.
Who has the smallest mass electrons protons or neutrons?
Electrons have the smallest mass of the three particles, with protons and neutrons having roughly 1836 times more mass than an electron.
