Electrons, due to their movement around the nucleus.

∙ 12y agoI'm going to assume you meant mass and not volume. The entire atom contributes the volume of an atom. That's what volume is.
The atom consists of three subatomic particles: electrons, protons and neutrons. Electrons have almost no mass and only contribute to the charge of the atom.
Neutrons and protons are the two particles that contribute to the mass. Both are found in the nucleus. Neutrons have no charge and are just there to make the atom heavy and keep the protons from falling apart. That's why it is sometimes referred to as "atomic glue". Protons also contribute to the mass.
Hope that helps.

∙ 12y agoNeutrons and Protons eache weigh approximately one Dalton. Electrons do have weight but it is so small a fraction of a Dalton that it is generally not included in any weight calculations.

What are the subatomic particles with no mass called?
All subatomic particles have mass.
What subatomic particles contribute to the mass of?
The atomic mass is the sum of the number of protons and the number of neutrons found in each atom of that element (electrons do not contribute). They are sometimes seen on periodic tables to have a decimal in the atomic number, this is for elements with more than one common isotope (an isotope of an element is the same number of protons but with a different number of neutrons), in which case an average of the common isotopes can be used.
What does subatomic particles contribute to the value of atomic mass and atomic number?
protons is the same number as the atomic number always and protons plus the average number of neutrons makes up the atomic mass
What particle have mass of lamu?
Subatomic particle
What two subatomic particle composed the mass?
Matter
What subatomic particle contributes alomst no weight to an atom?
The subatomic particles that contribute most almost no weight to an atom are electrons at various energy levels. Isotopes of the same element differ from each other only by the number of neutrons.

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 does subatomic particles contribute to the value of atomic mass and atomic number?
protons is the same number as the atomic number always and protons plus the average number of neutrons makes up the atomic mass
What subatomic particles has appreciable mass and lacks a charge?
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
What are the smallest objects?
That depends what you include under the term "objects". In general, those would be subatomic particles. Many of them are (in a sense) considered to have no volume. Some of them, such as photons and gravitons, have zero mass (rest mass; they will have some mass due to their energy).
What are the features of the subatomic particles?
Subatomic particles have mass, dimensions, spin, sometimes have an electrical charge.
Which subatomic paricle has the smallest mass?
Electrons
What particle have mass of lamu?
Subatomic particle
What is the equation for mass volume and density?
Mass = Density x Volume Density = Mass/Volume Volume = Mass/Density
Which subatomic particle has a mass of 1amu?
Protons and neutrons have the mass of 1 amu.
