They have mass, it is just too little in comparison to the mass of the neutron and protons to be taken into account. Therefore when measuring the mass of an atom, the mass of the electron are not used. (To be exact,9.10938188 × 10-31 kilograms, and the mass of proton is 1.67262158 × 10-27 kilograms.)

Why is it important for electrons to have no mass?
Electrons having mass is essential for understanding their behavior in the realm of particle physics. Mass affects various interactions of electrons, such as their ability to couple with the Higgs field to acquire mass or participate in the weak force interactions. Without mass, electrons would not be able to form stable atoms, and the entire foundation of chemistry and matter as we know it would be fundamentally different.
What has the smaller mass protons electrons or nutrons?
Electrons have the smallest mass compared to protons and neutrons. The mass of a proton is approximately 1836 times greater than the mass of an electron, and the mass of a neutron is slightly greater than that of a proton.
Do electrons have a large mass?
No, electrons are elementary particles with a very small mass. They have a mass of about 9.11 x 10^-31 kilograms, which is approximately 1/1836 times the mass of a proton.
Does electrons have the smallest mass?
Electrons have a very small mass compared to other subatomic particles like protons and neutrons. However, they are not the smallest known particles in terms of mass. The smallest known particles are neutrinos, which have a mass close to zero.
Do Electrons have weight?
Electrons have a mass of about 9.109389 * 10−31 grams.
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
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
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
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.
