Elektron is a subatomic particle that carries a negative electric charge. It is one of the fundamental building blocks of matter and is found in all atoms. Electrons orbit the nucleus of an atom, which is made up of positively charged protons and neutral neutrons. Their arrangement and behavior determine the chemical properties of elements. In addition to their role in forming atoms, electrons are essential in electricity and magnetism. They flow through conductors, creating electric currents that power devices. The study of electrons is crucial in fields like physics, chemistry, and electronics, influencing technologies such as computers and batteries.
