Explanation:
Decades before J.J. Thompson discovered the electron in 1897, French chemist André-Marie Ampère theorized that there must be an ‘electrodynamic molecule’ that’s responsible for electricity. This proved to be correct on a subatomic scale — as electrons get kicked out of their outer ‘valence’ shells, they travel to another atom, and this journey is known as electricity. Ampère is widely regarded as one of the founding fathers of electromagnetic in modern times.
André-Marie Ampère was an important physicist who helped lay the groundwork for electromagnetism and predicted the existence of electrons as subatomic particles. Ampère proposed that electricity and magnetism were closely linked phenomena that could be described by a unified theory. He formulated mathematical equations relating electric and magnetic fields that helped pave the way for Maxwell’s theory of electromagnetism.
Ampère also hypothesized that within atoms, tiny particles might be responsible for conducting electricity and magnetism. He believed these subatomic particles, which he called “electrions”, could circulate within conducting materials like metals. Ampère’s seminal ideas and theories were crucial steps towards the eventual discovery of electrons. Though the nature of electrions remained unclear, Ampère postulated that they might have properties like negative charge, small size, and ability to flow freely within atomic structures.
Decades after Ampère’s death, physicists like J.J. Thomson proposed that electrons were the fundamental subatomic particles that make up atoms and conduct electricity. Thomson showed that electrons have a negative electric charge, are very lightweight, and can be emitted from atoms. This evidence confirmed Ampère’s original hunches about the existence of tiny charged particles circulating within materials. Thomson’s discovery of the electron cemented Ampère’s legacy as a pioneer who helped lay the groundwork for modern particle physics and the field of quantum mechanics.
André-Marie Ampère was a pivotal figure in the development of electromagnetism. He proposed that electricity and magnetism were interconnected and could be described by a unified theory. Ampère also hypothesized the existence of tiny subatomic particles, called electrions, that could conduct electricity within atoms. Though the nature of electrions remained unclear, Ampère’s ideas were an important precursor to the eventual discovery of electrons by J.J. Thomson and others. Ampère helped establish electromagnetism as a field and took early steps towards realizing the importance of subatomic particles in physics. He represents a seminal moment of progress that influenced all of modern physics.
