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.
What else can I help you with?
Which subatomic particle has the smallest mass alpha particle neutron electron proton?
among these Electron has the least mass....
What particle is least massive?
The least massive principle atomic particle is the electron. Neutrons and protons are much more massive and are about equal in mass. Of course, there are even smaller particles such as quarks which are less massive than even electrons.
Nuclear radiation ranked from the greatest mass to the least mass is a- Xray gamma ray beta particle b- Xray beta particle gamma ray c- Alpha particle beta particle gamma ray d Beta alpha gamma?
The correct order is c) Alpha particle, beta particle, gamma ray. Alpha particles have the greatest mass, followed by beta particles, and then gamma rays which have no mass.
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
What particle in the atom is the least massive?
least - electron most - the top quark
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 found in an atom has the least mass?
the electron
Which in an atom has the least mass in an atom?
Which particle? The electron.
What subatomic particle has the less mass?
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
Subatomic particle that has the least mass?
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
Which subatomic particle has the smallest mass alpha particle neutron electron proton?
among these Electron has the least mass....
Which has least mass neutron protron electron or nucleus?
Well, that's kinda a trick question because an electron is pure energy. An electron particle is also the smallest of the 4, so its the electron (eventhough an electron is a weichtless particle such as a graviton or magneton! Hope I helped!!
What stable particle found in an atom has the least mass?
the electron
Which has the least mass protons neutrons or electrons?
This particle is the neutron.
What is the least mass?
The least mass refers to the smallest amount of matter that can exist for a given substance, typically measured in grams or kilograms. In the context of particle physics, it can refer to the mass of fundamental particles, such as electrons, which have a very small mass of about 9.11 x 10^-31 kilograms. In a broader sense, the least mass can also pertain to the minimum mass required for a stable system or object.
Which atomic particle has the least mass?
An electron has the least mass among the three fundamental particles of an atom, which includes protons and neutrons.
The amount of energy contained in the mass of a particle observed to be at rest is known as its?
rest energy
