It is electron. It's mass is negligibly small compared to that of proton and neutron.

Hence,it's contribution to atomic mass is not counted

Does proton have a smaller ma's or bigger mass?

A proton has a larger mass compared to an electron. Specifically, the mass of a proton is about 1836 times greater than that of an electron. In the context of atomic particles, protons are one of the heaviest components of an atom, alongside neutrons, while electrons are much lighter.


Is a particle lighter than an atom?

Yes, many particles are lighter than atoms. Subatomic particles, such as electrons and neutrinos, have much smaller masses compared to atoms. For example, an electron has a mass of about 1/1836 that of a proton, which is a major component of atomic mass. Thus, several fundamental particles are indeed lighter than atoms.


What has a relative mass of 1836 if the mass of electron is 1?

The particle with a relative mass of 1836 compared to an electron (which has a mass of 1) is the proton. In terms of mass, the proton is approximately 1836 times heavier than the electron, highlighting the significant mass difference between these two fundamental particles. This mass relationship is crucial for understanding atomic structure and the behavior of matter.


What is the difference between mass of hydrogen and mass of electron?

There are different isotopes of hydrogen. Assuming you mean the difference in atomic mass between a proton and an electron though, the atomic mass of a proton is about 1836 times greater (approx 1.007 amu), and the neutron is a little more than that (approx 1.009 amu).


What is the size order for these scientific particles Proton Neutron Atom Electron Nucleus?

IIRC Atoms (contains Protons/Neutrons and electrons) Nucleus contains Protons and Nuetrons Proton atomic size 1 Nuetron atomic size 1 electron atomic size 1/1836 i.e the proton is 1836 bigger than the electron

How many times a he atom is lighter than a haemoglobin molecules?

A hydrogen atom is about 1836 times lighter than a single hemoglobin molecule. This is because the atomic mass of a hydrogen atom is approximately 1 atomic mass unit (amu), while the molecular mass of a hemoglobin molecule is roughly 1836 amu.

Is a proton the least mass?

In an atom, there are 3 types of particles: protons, neutrons and electrons.Theoretically, protons and neutrons weight 1 Atomic Mass Unit. An electron weights 1/1836 of an Atomic Mass Unit. Therefore, in an atom, electrons weigh the least.


Are elections bigger or smaller then neutrons and protons?

Elections are much smaller than neutrons and protons. Neutrons and protons are subatomic particles found in the nucleus of an atom, while electrons orbit the nucleus in electron clouds. The electron is about 1/1836 times smaller in mass compared to a neutron or a proton.


Which particle or particles of an atom have little mass?
