What happens when you add an electron to its mass?
The mass of an electron is almost entirely negligible compared to the mass of an atom. I'm not sure if that's the question you were asking, but you can essentially ignore electron mass when calculating the mass of an atom; an electron's mass is only about 0.0005 amu, so even for the heaviest elements the total mass of the electrons is still a tiny fraction of an amu.
How does the mass of neutron compare to the mass of an electron?
The electron has only a small fraction of the mass of the neutron. The neutron is about 1837 times as massive as the electron. The proton is just a tiny bit less massive as the neutron, so the proton and neutron are said to have about the same amount of mass.
How does the mass of an electron compare to the mass of the neutron?
The electron has only a small fraction of the mass of the neutron. The neutron is about 1837 times as massive as the electron. The proton is just a tiny bit less massive as the neutron, so the proton and neutron are said to have about the same amount of mass.
When calculating an atomic approximate mass how is the mass of electron figured?
When calculating the atomic mass of an atom, the mass of an electron is typically considered negligible. This is because the mass of an electron is almost 2000 times smaller than the mass of a proton or neutron, which are the primary components used in determining the atomic mass of an atom.
How does the mass of the nucleus compared to the mass of the Atom?
The mass of the nucleus makes up most all of the mass of an atom. The only things outside the nucleus are the electrons. The mass of an electron is ~9.11E-31 kg. The mass of an electron is 1/1836 that of a proton.
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.
Why is mass number calculated with only the protons and neutrons and not electrons?
Because the mass of electron is negligible when compared to the mass of protons or neutrons.
Is the mass of a proton half the mass of a electron?
No. The mass of a neutron is far, far, far greater than the mass of an electron. In fact, the mass of a neutron is approximately about 1840 times greater than the mass of an electron. The particle that has exactly the same mass as an electron is its antiparticle, the positron.
Why are mass numbers whole numbers?
mass numbers are whole numbers because the mass number is number of protons in an atom, plus the number of neutrons. you can only have a whole neutron and or proton, therefore, all mass numbers are whole numbers.
How does the mass of an electron compare to that of a neutron?
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
What does Rutherford's model predict about the mass of electrons?
Rutherford's model only predicts that the mass of an electron is much smaller than the mass of the central nucleus.
Which of the subatomic particle is the lightest?
Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.109 × 10−31 kg, which is only 1/1,840the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.
