Yes, electrons have a mass, as everything has mass. However, an electron's mass is so small that it is considered to be 0.

How do you calculate the atomic mass of bromine?
To calculate the atomic mass of any element, add the no. of protons and neutrons. There sum will be the atomic mass. The mass of electrons is not counted towards the atomic mass.
An element's atomic mass does not include the mass of its?
...electrons, as they account for a negligible mass relative to the atom as a whole (electrons make up 1/1840th of the total mass, to be precise).
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."
What is the mass of an ion with 107 electrons?
electrons have negligible mass. the mass of the ion depends on how many protons and neutrons are present.
Protons and electrons have this?
Protons and electrons have mass and charge.
Why do you say the mass of any element is in the nucleus and you ignore the mass of the electrons?
The mass of any atom is in the nucleus because it contains both protons and neutrons. Protons and neutrons have a significantly greater mass than electrons do, so electrons are ignored when finding the mass of an atom.
Why is it important for electrons to have no mass?
Actually, electrons do have mass.
How many electron does it take to balance the mass of just 1 proton?
About 1837.This is why you can safely ignore the mass of electrons for any known element in rough calculations; the total mass of the electrons will be well under 0.1 amu.
How do you calculate the atomic mass of bromine?
To calculate the atomic mass of any element, add the no. of protons and neutrons. There sum will be the atomic mass. The mass of electrons is not counted towards the atomic mass.
How is mass related to electrons?
because the electrons plus the nuetrons equal the mass
An element's atomic mass does not include the mass of its?
...electrons, as they account for a negligible mass relative to the atom as a whole (electrons make up 1/1840th of the total mass, to be precise).
A neutral atom of gold has a mass number of 197 and has 118 neutrons how many electrons does it have?
Any neutral atoms has the same number of electrons as protons, and any atom has a number of protons equal to the difference between its mass number and neutron number. Therefore, this atom has 197 - 118 = 79 electrons.
Is the number of electrons the same thing as the atomic mass in an atom?
No, electron count really doesn't have anything much to do with atomic mass. Let's look. Most of the mass of any atom is concentrated in the nucleus. It's the protons and neutrons there that give the atom "weight" and the electrons contribute almost nothing. Additionally, electrons can be loaned or borrowed by atoms, and this changes their mass very little. The number of electrons is not very "connected" to atomic mass of an atom.
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
