The up and down quark accounts for most of an atoms mass. Two up quarks and one down quark forms a proton, and one up quark and two down quarks forms a neutron. Protons and neutrons form the nuclei of atoms, and comprise most of their mass, along with the binding energy holding them all together.

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 smallest of the three subatomic particles and are not counted in the mass of an atom?
electrons
Which subatomic particles have a mass so small it typically is ignored?
Electron
What are particles?
Particles are small pieces of matter. Depending on the context, it may refer to pieces of dust, to atoms or molecules, or to subatomic particles such as protons, electrons, quarks, etc.
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.
What subatomic particles responsible for most of an atoms mass?
These particles are the protons and neutrons.
Which subatomic particles are used to determine an atoms mass number?
Two particles are considered. they are protons and nrutrons
What are the subatomic particles with no mass called?
All subatomic particles have mass.
Which one of the subatomic particles is the heaviest?
I think the "Top" quark is probably the heaviest, which has a mass about that of 170 hydrogen atoms.
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 do atoms subatomic particles differ in?
They differ by mass, electrical charge, dimensions, location in atom, type of qurks contained.
What are the features of the subatomic particles?
Subatomic particles have mass, dimensions, spin, sometimes have an electrical charge.
Which two subatomic particles make up most of the atoms mass Where are they located?
These particle are neutrons and protons; they are located in the atomic nucleus.
What subatomic particles are used to calculate the mass of an atom?
Hey! The excepted banacular is gay. Don't call them atoms that's just mean.
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 has appreciable mass and lacks a charge?
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
