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.
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
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."
Do electrons have mass?
Yes, electrons have a mass of 9.1094 X 10−31 kg.
When calculating an atoms approximate mass how is the mass of electrons figured?
electrons are the same as protons
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
What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
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 5.010 18 electrons?
The mass of 5.1018 electrons is 45,546 910 75.10-13 kg.
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.
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.
