What are the smallest of the three subatomic particles and are not counted in the mass of an atom?
electrons
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.
Which subatomic particles have a mass so small it typically is ignored?
Electron
Are subatomic and little particles the same thing?
Atoms are composed of protons, electrons and neutrons (save hydrogen-1, which lacks any neutrons). Protons and neutrons are baryons, which are made up of three quarks. Having said that, the quark, which is a fundamental particle, is smaller than an atom by a great deal. Further, the quark is smaller than either a proton or neutron, as both are made of three quarks. The electron is a fundamental particle, and it is smaller still than a quark.When we look at the fundamental particles as they are described in the Standard Model, only the photon and gluon, which are force carriers, are smaller. It should be noted that the way we relate "smaller" in this case is by stating a mass-energy equivalence and describing the mass of the fundamental particles in terms of energy.

Does electron mean a subatomic particle with a negative charge?
Electrons are negatively charged subatomic particles, but have almost no mass. The mass of an electron is about 1/2000 that of a proton or neutron. The neutron is the most massive of the subatomic particles at 1.6755 x 10-24 grams.
Which subatomic particles has the lest mass?
In the atom the electron is the lightest.
What do the three of the subatomic particles have in common?
They have a mass and are components of the atom.
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
What are the smallest of the three subatomic particles and are not counted in the mass of an atom?
electrons
What are the two principal components of the nucleus of the atom?
The two principal components of an atom at a subatomic level are Protons and Neutrons. Protons are subatomic particles with a mass of 1 and a charge of 1+ Neutrons are subatomic particles with a mass of 1 and a charge of 0 or neutral
What are the two subatomic particles with a mass?
In the atom, protons and neutrons; the mass of the electron is very small.
What is a subatomic particles with almost no mass?
The electron is the lightest particle in the atom.
What are the subatomic particles with no mass called?
All subatomic particles have mass.
Subatomic particles responsible for most of an atom's mass?
Protons and neutrons.
How many subatomic particle would be present in an atom of helium with a mass of 4 amu?
An atom of helium with a mass of 4 atomic mass units (amu) would typically contain 4 subatomic particles. Two of these particles would be protons, two would be neutrons, and two would be electrons.
What are the relative atomic mass of subatomic particles in atom?
neutrons are heavier than protons by a bit more than the mass of electron.
What is the subatomic particle that has the greatest mass?
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.
