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.
Of the neutron, proton, and electron, the electron has the smallest mass.
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.
electrons are a 2000th of the mass of a proton/neutron. Because of this very low mass, electrons dont affect the mass number of elements on the periodic table
Electrons have such a small mass relative to protons and neutrons that they are typically not included in calculations of atomic mass. The mass of electrons is about 1/1836 of the mass of a proton or neutron, so their contribution to the overall mass of an atom is negligible. Instead, atomic mass is primarily determined by the sum of the number of protons and neutrons in the nucleus of an atom.
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.
because the electrons plus the nuetrons equal the mass
depends on the electrons
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."
Yes, electrons have a mass of 9.1094 X 10−31 kg.
electrons are the same as protons
electrons have no mass
The sum of masses of protons, neutrons and electrons.
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.
The mass of 5.1018 electrons is 45,546 910 75.10-13 kg.
no electrons have mass, about 1/1800 that of a proton or neutron.
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.
