The three particles that make up an atom are protons, neutrons and electrons. Protons and neutrons both have a mass of 1 unit, whereas the mass of an electron is 1/1837 of that of a proton or a neutron. Therefore, the electron has the least mass as its mass is considered negligible.

Particle with a large mass and a posiive charge?
A particle that has a large mass and a positive charge is known as an alpha particle. These particles contain 2 protons and 2 neutrons which are bound together to form an identical particle to a helium nucleus.
A particle that has mass and a positive electrical charge?
There are three atomic particles with mass, the proton, neutron and electron. Of these three, the proton is the particle with a positive charge.
What subatomic particles has appreciable mass and lacks a charge?
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
What is the mass of one molecule of glucose?
Each atom has its own RELATIVE MASS.This is the mass of each atom in comparison to carbon.C6H12O6 is the formula of a glucose molecule.C6 means there are 6 carbon atoms. 1 carbon atom has a mass of 12.So 6 * 12 = 72H12 means there are 12 hydrogen atoms. 1 hydrogen atom has a mass of 1.So 12 * 1 = 12O6 means there are 6 oxygen atoms. 1 oxygen atom has a mass of 16.So 6 * 16 = 9672 + 12 + 96 = 180So a molecule of glucose has a relative molecular mass of 180.Hope this helps
Any element can always be identified by its?
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
Which in an atom has the least mass in an atom?
Which particle? The electron.
What particle found in an atom has the least mass?
the electron
What stable particle found in an atom has the least mass?
the electron
Subatomic particle that has the least mass?
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
When a beta particle is released from an atom does the atom gain or lose mass?
When a beta particle is released, the atom's mass remains approximately the same because it loses an electron, which has such a small mass in comparison to the whole atom that it is negligible.
Which particle has the least amount of mass?
The 'rest mass' of the photon is zero ... but the photon is never at rest, and it has plenty of mass at the speed of light, at which it is always traveling. so that let's the photon out. Amongst particles that actually have rest mass, but not much of it, the neutrino probably has the least.
Which particle of an atom has the less mass?
The Electron.
What sub atomic particle does not particitpate in the calculation of mass of atom?
Mass of electron is not included for the calculation of mass of an atom.
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.
What particle determines the mass along with the protons of an atom?
The particle is called the "Quark"
What particle of an atom has the most mass?
It would be neutrons.
What has the least mass in an atom?
The election within an atom would have the least mass. Protons and neutrons have a mass roughly that of 1amu, while an electron's is 1/1840 of an amu.
