Though today we know that an atom is made up of 3 types of sub-atomic particles (electrons,protons and neutrons) but it is found that each electron has a mass very less in comparison to the mass of other particles.So, its mass is taken to be negligible and is not counted to be contributing to mass of entire atom.On other hand, protons and neutrons have noticeable masses and are almost equal to each other in masses.These both are found in nucleus of atom and are considered to be contributing to the mass of the atom.

Protons and neutrons contribute to the Atomic Mass of an atom. Electrons, despite having mass, contribute negligibly to the overall atomic mass due to their much smaller mass compared to protons and neutrons.

What are the Subatomic particles with no charges?

Neutrons are subatomic particles with no charge. They are found in the nucleus of an atom along with protons and contribute to the atomic mass of an element without affecting its charge.


Is sodium a subatomic particle?

No, sodium is not a subatomic particle. Sodium is a chemical element with the symbol Na and atomic number 11. Subatomic particles are particles smaller than an atom, such as protons, neutrons, and electrons.


What are the subatomic particles in atomic structure?

The subatomic particles in an atom are protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit around the nucleus in various energy levels or shells.


Which sub atomic particles cause isotopes to appear?

Isotopes are caused by variations in the number of neutrons in an atom's nucleus. Neutrons are subatomic particles that do not carry an electric charge and contribute to an atom's mass. The different number of neutrons in isotopes result in variations in atomic mass.


What subatomic particles gives an atom its identity?

Protons are the subatomic particles that give an atom its identity. The number of protons in the nucleus determines the element's atomic number, which in turn defines the specific type of atom.


What subatomic particles contribute to the mass of?

The subatomic particles that contribute to the mass of an atom are protons, neutrons, and electrons. Protons and neutrons are located in the nucleus and account for most of the mass, while electrons have negligible mass but contribute to the overall charge and stability of the atom.


What of these subatomic particles are represented by atomic number?

Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.


What is ment by atomic number?

Atomic Number is the amount of Protons (positively charged subatomic particles) contained in the nucleus of an atom.


Are the protons in the nuecleus?

Yes, protons are positively charged subatomic particles found in the nucleus of an atom. They contribute to the overall positive charge of the nucleus and determine the atomic number of an element.


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.


Is a subatomic particle an atom?

No; an atom contain subatomic particles.


How does subatomic particles relate with the atom?

The atom contain subatomic particles as neutron, proton, electron.
