DSFTM @ MEMEX – The atom

4th Episode Memex RaiScuola: The atom

Matter is it made of atoms. The atom is the smallest portion of matter that retains all the characteristics of a single element. Every atom is composed of a core and one or more electrons arranged on circular orbits. The core that is made from high-density positively charged particles, protons, and particles with charge neutral calls precisely neutrons. The atom is not a discovery of modern science.
