Why ins't the third subatomic particle counted in the mass of an atom?

Electrons have a mass of only about 0.0005 as much as protons or neutrons.

What is the lightest subatomic particle of an atom?

The lightest subatomic particle of an atom is the electron. It has a very small mass compared to protons and neutrons, making it a key component in determining the chemical properties of an atom.

What is the subatomic particle that has the greatest mass?

The subatomic particle with the greatest mass is the neutron. Neutrons are found in the nucleus of atoms along with protons, but they are slightly more massive than protons. Electrons, which orbit the nucleus, have much less mass compared to neutrons and protons.

Which of the subatomic particle is the lightest?

Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.109 × 10−31 kg, which is only 1/1,840the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.

How many subatomic particle would be present in an atom of helium with a mass of 4 amu?

6 subatomic particles. 2 protons and 2 neutrons (that accounts for the mass of 4 amu) as well as 2 electrons.

What is a neutron in an atom?

The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton.
