He was the first to discover that all matter is made up of invisible particles called atoms. He created the name "atom" from the Greek word "atomos", which means uncuttable. He also discovered that atoms are solid, insdestructable, and unique. HIs model was just a round solid ball. Democritus didn't know about a nucleus or electrons, all he knew was that everything is made of atoms. doggostevenson https://padlet.com/doggostevenson/wt91fyukn249/wish/134256136 2016-10-31 15:20:54 UTC https://padlet.com/doggostevenson/wt91fyukn249/wish/134256136
