The photon. This refers to the "rest mass"; since the photon has energy, it also has an associated mass. But the "rest mass" or "invariant mass" is zero.

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
What are the smallest of the three subatomic particles and are not counted in the mass of an atom?
electrons
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.
How are subatomic particles different?
Differences are in: mass, electrical charge, life time, spin etc.
What are the subatomic particles with no mass called?
All subatomic particles have mass.
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
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.
What are the features of the subatomic particles?
Subatomic particles have mass, dimensions, spin, sometimes have an electrical charge.
What subatomic particles are similar in mass?
neutrons and protons
Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
What subatomic particles responsible for most of an atoms mass?
These particles are the protons and neutrons.
What subatomic particles has appreciable mass and lacks a charge?
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
Which statement about subatomic particles is not true?
Subatomic particles are the same size as basketballs.
Of the three main subatomic particles the has the least mass?
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 subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
What are the 2 subatomic particles with mass of 1?
Protons and neutrons
