Detailed explanation-3: -Electrons revolve around the nucleus in a fixed path called as orbits. They are also called shells.

Detailed explanation-4: -Electrons are one of three main types of particles that make up atoms. Unlike protons and neutrons, which consist of smaller, simpler particles, electrons are fundamental particles that do not consist of smaller particles. They are a type of fundamental particle called leptons.

Detailed explanation-5: -The nucleus is heavy and positively charged. The electron is light and negatively charged. They attract, so if the electron moves sideways at the right speed it will bend toward the nucleus and just keep on bending in a circle, the same as a satellite orbiting earth.
