Electrons, protons, and neutrons are three subatomic particles of an atom. if the atom undergoes a change and becomes a positive ion, which subatomic particle is lost in this process? neutron proton electron

Answer : The correct option is, Electron.

Explanation :

There are three subatomic particles of an atom which are electrons, protons and neutrons. The protons are positively charged, the electrons are negatively charged and neutrons are neutral (no charge).

A neutral atom is an atom that has same number of electrons and protons.  When a neutral atom gain an electron, it becomes a negatively charged ion.  When a neutral atom lose an electron, it becomes a positively charged ion. That means the atom change when the electron is lost or gained.

Hence, if the atom undergoes a change and becomes a positive ion, in this process the lost subatomic particle is electron.
