Which has the smallest mass?
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
Which subatomic particle has the smallest mass alpha particle neutron electron proton?
among these Electron has the least mass....
What the smallest particle in a atom?
Size on the scale of atoms is very hard to define. The electron has zero mass. Quarks have varying amounts of mass.
Are atoms the smallest particles of matter?
No. The smallest particle of matter appears to be the electron neutrino, with a mass somewhat less than 2.2 eV. Even the electron, at 511 eV, is massive, compared to the neutrino.
What subatomic particle Has the smallest relative mass?
In the atom the electron is the lightest.
Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?
electron
Smallest known particle that makes up protons and neutrons?
Of those three the electron is the least massive.
Does subatomic particles have the smallest mass of any subatomic particle?
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
Where can you find the smallest subatomic particle?
This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.
What is the smallest particle of the atom?
I'm not exactly sure but it's probably: electrons, neutrons, and protons.The electron is the smallest particle of the atom, in the traditional sense. However, the neutrino is far smaller than the electron, and is thus the smallest particle. You could also argue that the photon, with zero rest mass, is actually the smallest, but that's a quantum mechanics question that seems to be beyond the scope of this question.
Which subatomic particle is least massive?
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or atomic mass units.
Is hydrogen the smallest particle of an element?
An average hydrogen atom consists of 1 proton and 1 electron. The 1 proton accounts for nearly all of that atom's mass. The 1 electron has only about 1/2000th the mass of the proton. That's about 0.0005 of the total atomic mass.
