Question

The ratio of charge and mass would be greater for?
A. Proton
B. Electron
C. Neutron
D. Alpha

Answer 1

Hint: We know that the atomic particles are made up of three smallest units, they are the electron, neutron and proton. The neutron has a neutral charge. The proton has a positive charge while the electron has a negative charge.

Complete answer
As we all know, there are mainly three components which are present in an atom. The atom is one of the smallest units of matter. The charge is the property by which we get to know about the electromagnetic attractions between the particles. There are mainly two types of charge, one is positive, and the other is negative. Generally, the negative charge is the property of electrons, while the positive charge is the property of protons. When the mass of the particle is less, then the ratio of charge to mass is high.
The increasing order of the ratio of charge to mass is shown below.
Neutron < Alpha particle< Proton < Electron
Thus, the ratio of charge and mass would be greater for electrons.

Hence, the correct option for this question is B, that is the electron.

Note:
There are three subatomic particles. They are present in an atom. In an atom, protons which bear the positive charge and neutrons which are neutral together comprise the nucleus. Electrons which bear the negative charge present outside the nucleus in an orbital. The electron is one of the subatomic particles which orbits in the shell of the atom. The weight of electrons is lesser than the nucleus of the atom.
