What is Atomic Theory and Elements Overview about?
1) An atom is the smallest unit of matter that composes elements. It contains a nucleus with protons and neutrons surrounded by orbiting electrons. 2) A chemical element is a species of atom that has the same number of protons. There are over 100 elements that make up all matter. 3) The idea of atoms was first proposed by Democritus in the 5th century BCE, though it was not widely accepted until scientists like Dalton developed the first modern atomic theory in the 19th century.
