True!
No, the electron cloud is not heavy. An electron weighs approximately 2000 times less than a proton or a neutron, so almost all the weight of an atom lies in the nucleus, not in the electron cloud.
The subatomic particle that fits this description is the electron. Electrons have a negative charge, are found outside of the nucleus in electron shells, and have a very small mass compared to protons and neutrons.
An electron has a mass of 9.109 X 10-31 kg, approximately 1⁄1840 the mass of a proton. However, the term mass number doesn't apply to electrons, it applies to atomic nuclei. The mass number of a nuclear isotope is the total number of protons and neutrons, together known as nucleons, of the isotope, and is denoted by (A).
among these Electron has the least mass....
No, the mass of an electron is roughly 1/1836 the mass of a proton.
Of the particles you mentioned, the electron has the smallest mass.
The electron is the lightest particle in the atom.
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.
Mass= mass of electron Speed= Almost equal to that of light
1.66 X 10 -27 kg (mass of proton)/9.109 X 10 -31 kg (mass of an electron) = 1822 ----------------------the mass of a proton is almost 2000 times the mass of an electron
almost nothing 1/1840
because the electron has such a tiny ity bity mass that it adds almost nothing to the atomic mass!
The lightest subatomic particle is the electron.
yes the mass of an electron is much tinnier fraction of the mass of an atom
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.
A electron is a subatomic particle outside the nucleus carrying a negative charge and very little mass. Other mass is negligible mass or a negative charge.
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.
