GENERAL KNOWLEDGE

Detailed explanation-1: -There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.

Detailed explanation-2: -Thus, The negatively charged particles present in an atom are called electrons.

Detailed explanation-3: -A negatively charged atom is called an anion. Anions are usually formed when non metals accept additional electrons from metallic elements. These anions are then capable of forming ionic bonds with the metals which lost electrons to become positively charged cations.

Detailed explanation-4: -Miller, a UW physics professor, has found that the neutron has a negative charge both in its inner core and its outer edge, with a positive charge sandwiched in between to make the particle electrically neutral.
