EVERYDAY SCIENCE

Detailed explanation-1: -Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.

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: -Electron: Electrons are the negatively charged particles found outside the nucleus that revolve in specific circular orbits with a fixed energy level.

Detailed explanation-4: -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.
