Both the Photon and the Gluon have zero mass.
Theoretically, the photon has zero rest mass (related to the fact that the electromagnetic force has unlimited range).
The current experimental upper limit is 10−18 eV/c2, or about 2×10-54 kg. For comparison, that means the photon is at least 5×1023 times lighter than the electron.

What else can I help you with?
What subatomic particle Has the smallest relative mass?
In the atom the electron is the lightest.
What is the smallest part of the atom that has almost no mass?
The smallest part of an atom would be a quark. Quarks are either up or down quarks, and have virtually no mass. Neutrinos have even less mass, but are not part of an atom.
What is the smallest particle a substance?
An atom is the smallest particle of a substance.
What is the smallest particle of the element iron that can still be classified as iron?
An iron atom is the smallest iron particle that still has the properties of iron.
What is the smallest particle of the atom?
I'm not exactly sure but it's probably: electrons, neutrons, and protons.The electron is the smallest particle of the atom, in the traditional sense. However, the neutrino is far smaller than the electron, and is thus the smallest particle. You could also argue that the photon, with zero rest mass, is actually the smallest, but that's a quantum mechanics question that seems to be beyond the scope of this question.
Why it is not possible to find the absolute mass of an atom?
It is the smallest particle
The smallest particle of an element is called?
The smallest particle of an element is called an atom.
What subatomic particle Has the smallest relative mass?

What is the smallest part of the atom that has almost no mass?
The smallest part of an atom would be a quark. Quarks are either up or down quarks, and have virtually no mass. Neutrinos have even less mass, but are not part of an atom.
Which particle has the smallest mass atoms or electron?
An electron has a much smaller mass than any atom.
Is proton the smallest particle in a chemical element atom?
The smallest particle in the atom is the electron.
What is the smallest particle a substance?
An atom is the smallest particle of a substance.
What in an atom?
An atom is a particle, the smallest particle that can exist by itself.
What is the smallest particle of the element iron that can still be classified as iron?
An iron atom is the smallest iron particle that still has the properties of iron.

Is for all elements the smallest particle that can exist independently is an atom?
No, for all elements the smallest particle that can exist independently is an atom.
How do you explain an atom?
atom is the smallest particle of matter
