  8. Dalton’s Atomic Theory element is made up of ATOM… the smallest particle in matter Atomic Models Thompson’s – Plum Pudding atoms contain negatively charged ELECTRONS Rutherfored’s – Planetary Model atom is like solar system with NUCLEUS in centre Bohr’s – Atomic Model atom is like solar system … electrons move in a fixed orbit Electron Cloud electrons form a cloud around the nucleus

  9. The Atom • ATOM – smallest particles of an element that have the properties of the element • NUCLEUS – dense region at centre of atom and contains → PROTONS– positively charged → NEUTRONS– neutrally charged • ELECTRONS – negatively charged particles located around the nucleus
