GENERAL KNOWLEDGE

Detailed explanation-1: -In physics, a charged particle is a particle with an electric charge. It may be an ion, such as a molecule or atom with a surplus or deficit of electrons relative to protons. It can also be an electron or a proton, or another elementary particle, which are all believed to have the same charge (except antimatter).

Detailed explanation-2: -Electrically charged particles generally referred to as ions. Since thermosphere has ions, it is also called as Ionosphere.

Detailed explanation-3: -When an atom loses or gains an electron, ions are formed. If an atom loses electron it forms positive charge and if gains electron it forms negative charge. An atom which carries charge on it is known as ion.

Detailed explanation-4: -Positively charged ions are called cations; negatively charged ions, anions.

Detailed explanation-5: -Cations are positively charged ions. They are formed when a metal loses its electrons.
