Electrons are tiny, negatively charged particles that orbit the nucleus of an atom, which is made up of protons and neutrons. They play a crucial role in electricity, as the movement of electrons through materials creates electric current. Electrons are so small that they cannot be seen with the naked eye, but they are essential for the structure of matter and the behavior of atoms.
In addition to their role in electricity, electrons are involved in chemical reactions. When atoms bond to form molecules, it is often the electrons that interact and share between them. This interaction helps create everything from the air we breathe to the food we eat, making electrons vital for life on Earth.
