The mass number of an atom is the total count of its protons and neutrons, which are collectively known as nucleons. Protons are positively charged particles found in the nucleus, while neutrons are neutral particles that also reside in the nucleus. Electrons, which are negatively charged, are not included in the mass number because their mass is negligible compared to that of protons and neutrons.

3 different subatomic particles from which atoms are made?
Protons, neutrons, and electrons are the three subatomic particles that make up atoms. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Together, these particles combine to form the structure of an atom.
What are the two subatomic particles that make up the nucleus?
Protons and neutrons are the two subatomic particles that make up the nucleus of an atom.
What is the name of the particle which makes up all other subatomic particles?
Quarks are the particles that make up protons and neutrons. There are no particles, as far as we know, that make up electrons.
What is the subatomic particles that make up atoms are neutrons in electrons and these?
protons
Three subatomic particles that make up an atom?
Protons, neutrons, and electrons.
What combines to make an molecule?
Atoms combine to form molecules and atoms are made of subatomic particles (protons, neutrons & electrons).
3 different subatomic particles from which atoms are made?
Protons, neutrons, and electrons are the three subatomic particles that make up atoms. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Together, these particles combine to form the structure of an atom.
What small subatomic particles are in the protons and neutrons?
The subatomic particles found in protons and neutrons are quarks. There are two types of quarks that combine to make either particle, up and down quarks. Protons are 2 ups and a down and neutrons are 2 downs and an up.
Subatomic particles bigger than molecles?
Subatomic particles are smaller than molecules and are the building blocks of atoms. Protons, neutrons, and electrons are examples of subatomic particles found in atoms. There are no known subatomic particles that are bigger than molecules.
Are photos made of subatomic particles?
No, photos are not made of subatomic particles. Photos are composed of photons, which are massless particles that carry electromagnetic force. Subatomic particles refer to particles like electrons, protons, and neutrons, which make up atoms.
What is the smallest part of a comet?
The smallest part of a comet is likely the dust particles that make up its coma, which is the cloud of gas and dust that surrounds the comet's nucleus. These dust particles can be as small as a few micrometers in size.
What are the two subatomic particles that make up the nucleus?
Protons and neutrons are the two subatomic particles that make up the nucleus of an atom.
What subatomic particles make up the atom?
protons, neutrons and electrons are the main subatomic particles of the atom. There are the same number of protons as electrons, which is equal to the atomic number. The number of neutrons may vary according to the isotope of the element.
What are the 3 subatomic particles that make an atom?
These particles are: neutron, proton, electron.
What is the name of the particle which makes up all other subatomic particles?
Quarks are the particles that make up protons and neutrons. There are no particles, as far as we know, that make up electrons.
What are subatomic structures called?
Subatomic structures are called particles, such as protons, neutrons, and electrons. These particles make up atoms, which are the building blocks of matter.
What is the smallest out of atom subatomic particle molecule and cell?
The subatomic particles are the smallest from the list given. The subatomic particles protons, neutrons, and electrons make up atoms, atoms make up molecules, and molecules make up organelles, and organelles make up cells.
