The mass of an electron is 9.12 x 10-31 kg
The mass of one electron is about 9.11E-31 kg. That's 0.000000000000000000000000000000911 kg. 911 billionths of a trillionth of a trillionth kg.
The mass of an electron is 9.107 x 10-31 kg.
1.66 X 10 -27 kg (mass of proton/neutron)/9.109 X 10 -31 kg ( mass of electron) = 1822 times greater ===============
The electron has a charge of -1; but the electron has a mass.
The mass of a proton is 2000 times the mass of an electron. Mass of electron: 9.10938 * 10-31 kg Mass of proton: 1.67262 * 10-27 kg Mass of neutron: 1.67493 * 10-27 kg Note that protons and neutrons weigh approximately the same (neutrons are slightly heavier), but electrons are MUCH lighter than both of them. The MASS of the electron is much smaller than neutrons and protons. It is common, but incorrect, to use mass and weight interchangeably. They are not synonymous.
Electron has a mass of about 9.10938215 × 10−31 kg.
Kg is the SI unit for mass.
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
The mass of one electron is about 9.11E-31 kg. That's 0.000000000000000000000000000000911 kg. 911 billionths of a trillionth of a trillionth kg.
No, there are the same number of protons and electrons in an atom, but I don't think that they have the same mass. You're right, an electron is 1,836 times lighter than a proton.
9.109382x10^-31 kg
To find the number of electrons in 1 gram, first calculate how many electrons are in a single electron's mass (9.11 x 10^-31 kg). Then, divide the mass of 1 gram (0.001 kg) by the mass of a single electron to determine the number of electrons in 1 gram. This calculation yields approximately 5.48 x 10^22 electrons in 1 gram.
Protons and Neutrons have around the same mass (1.67*10-27 kg). An electron's mass is 1/1833th the mass of a proton, or 9.11*10-31 kg.
1/1840 the mass if a hydrogen atom.
1.66 X 10 -27 kg (mass of proton/neutron)/9.109 X 10 -31 kg ( mass of electron) = 1822 times greater ===============
1 over 1,836 AMUAnother answerIt's negligible. It has such a low amu that it is not a factor of the overall atomic mass of an 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.
