The proton is slightly less massive than the neutron, and the electron is many, many times less massive than either of them. That makes the electron the smallest of the "standard" particles that make up atoms. There are many smaller particles in what is called the particle zoo, but it is hard to sort them out as they are all uniformly unstable and disappear in very short periods of time. The electron is the least massive of the stable subatomic particles that make up the nucleus.
Note: We added the last part because the neutron is not stable outside the nucleus of the atoms that it makes up. But of the "big three" particles that are the building blocks of the atom, the neutron, proton and electron, the electron is smallest. It's less than 1/1800th the mass of a proton.

What is the smallest unit measurement?
a mole in the term of molar mass which measures subatomic particles. stated as gram per mole
What did Democritus name the smallest particles of matter?
Atomos is the name Democritus gave the smallest particles.
Is it true that atoms are the smallest particles on the planet?
No It is not true that atoms are the smallest particles in the planets. The smallest particles are electrons, protons, neutrons, and others.
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.
The smallest particle in physics?
That depends. The smallest particle in the classic physics is te atom. In the modern physics is the quark (quark is the composition of an eletron). WHAT IS THE SMALLEST PARTICLE The quark
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.
Of the electron the neutron and the proton which has almost no mass?
Of the particles you mentioned, the electron has the smallest mass.
Smallest particles with very little mass and a positive charge?
proton
What are the smallest of the three subatomic particles and are not counted in the mass of an atom?
electrons
What series lists particles in order from smallest to greatest mass?
Electron, proton, nucleus, atom
What series lists particles in order from the smallest to greatest mass?
Electron, proton, nucleus, atom
What is the series lists particles in order from smallest to greatest mass?
Electron, proton, nucleus, atom
Can you list particles from smallest to greatest mass?
electrons are the lightest then protons then neutrons
What mixture has the smallest particles?
COLLOIDS
Which series list particles in order form smallest to greatest mass?
The Standard Model of Particle Physics gives a good list of particles and their masses.
Which particle has the least mass and where is this particle located in the atom?
The smallest particles that have been discovered and that don't only exist in theory are the quarks. They are what make up protons, neutrons, all kinds of baryons, and a few other categories of particles. But there is a theory of smaller particles that make up quarks, electrons, and other particles that were previously believed to be fundamental (But, again, these particles only exist in theory). These particles are to be called "rishons" if discovered.
Is the smallest particles in a compound are protons?
The smallest particles in a compound are electrons.
