Detailed explanation-1: -Electrons are negatively charged particles that generally orbit the nucleus of an atom. Electrons are much smaller than protons or neutrons.

Detailed explanation-2: -The nucleus of an atom is surrounded by a cloud of electrons. Remember, electrons are negatively-charged and are attracted to the positively-charged protons in the nucleus. An atom is considered to be electrically neutral if it has an equal number of protons and electrons.

Detailed explanation-3: -Electrons have a negative charge but are extremely small and have a mass only 1/1850 that of a proton or neutron. They are so small that for practical purposes they do not contribute to the mass of the atom. Electrons move around the nucleus at tremendously high speeds, actually travelling at near the speed of light.

Detailed explanation-4: -An electron is a negatively charged particle that travels in the space around the nucleus. In other words, it resides outside of the nucleus. It has a negligible mass and has a charge of –1.
