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 has mass but no volume?
Light has mass but no volume. Although light particles called photons have energy and momentum which contribute to their mass, they are considered massless particles because they have zero rest mass and do not occupy physical space.
What subatomic particle has the less mass?
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
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
Which subatomic particle has a charge of 0 and a mass of 1 atomic mass unit?
A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
What are the Subatomic particles with no charges?
Subatomic particles with no charges are neutrons
What subatomic particles contribute to the mass of?

What two subatomic particles do you add together to get the mass number?
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
What two subatomic particles are added together to determine the mass number?
The two subatomic particles added together to determine the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but both contribute to the mass of an atom.
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.
Which subatomic particles have mass and re included in the calculation of the atomic mass number?
Protons and neutrons are the subatomic particles that have mass and are included in the calculation of the atomic mass number. Electrons have very low mass compared to protons and neutrons and are usually not included in the atomic mass calculation as they contribute very little to the overall mass of an atom.
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 has mass but no volume?
Light has mass but no volume. Although light particles called photons have energy and momentum which contribute to their mass, they are considered massless particles because they have zero rest mass and do not occupy physical space.

Which subatomic particle has a charge of 0 and a mass of 1 atomic mass unit?
A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
Volume and mass of a neutron?
A neutron has a mass of approximately 1.675 x 10^-27 kilograms. Neutrons do not have a well-defined volume like solid objects since they are subatomic particles with wave-particle duality. Their size can be described by their interactions with other particles rather than a specific volume measurement.
