electrons
Virtually all of the mass of an atom is carried by the proton and the neutron. The electron has very, very little mass relative to these two particles.
An electron has the least mass among the three fundamental particles of an atom, which includes protons and neutrons.
The largest subatomic particle (by mass) is the proton. The mass of subatomic particles is measured in atomic mass units (amu). The proton has a mass of 1.007 amu, the neutron has a mass of 1 amu, and the electron has a mass of .0005 amu.
The Electron.
Basically nucleus is present in the centre of an atom which occupies very little space but it is responsible for most of the mass of atom. Its size can be assumed almost of a cricket ball IF atom is assumed as the stadium. being so small it still has a very complicated structure. It mainly contains 2 fundamental particles neutron - having no charge and mass=1.67493 x 10-27kg and proton having mass=1.67262 x 10-27kg and charge= +1.
Virtually all of the mass of an atom is carried by the proton and the neutron. The electron has very, very little mass relative to these two particles.
These particles are protons and neutrons.
In the atom the heaviest particle is the neutron but the proton is close.
The electron is the lightest particle in the atom.
Neutrons are the particles that contribute to the mass of an atom, along with protons. Neutrons have a similar mass to protons, but they do not have a charge. The number of protons and neutrons in an atom's nucleus determines its atomic mass.
These particles are proton and neutron.
An electron has the least mass among the three fundamental particles of an atom, which includes protons and neutrons.
A proton is a positively charged particle in the center of an atom. A neutron is another particle in the center of an atom that has no charge, but still has mass. Each particle, sometimes called a subatomic particle, has a mass of one AMU. The sum of these is the mass of one atom of an element. Electrons, the particles orbiting the nucleus, where protons and neutrons reside, are not taken into account in massing because they are so small.
It is called the nucleus and has a mass unit number of one.
Which particle? The electron.
The particle you are referring to is likely a proton. Protons are subatomic particles found in the nucleus of an atom and have a positive electrical charge. They also have mass, although their mass is much smaller than everyday objects.
The electron. There are three particles in an atom , they are:- Proton ; carries a charge of (+), and has an arbitrary mass of '1' Neutron ; carries no charge (o) , and has an arbitrary mass of '1' The above two particles are found the the nucleus of an atom, and are collectively named 'nucleons'. Electron ; carries a charge of (-), and has an arbitrary mass of 1/1860. It is found outside the nucleus of an atom.
