ATOMIC STRUCTURE MATTERVILLE NUCLEUS ARCADE MATTERVILLE NUCLEUS ARCADE NUCLEUS ARCADE 18 1st Verse: They’re tiny and they’re teeny, Much smaller than a beany, They never can be seeny, The Atoms Family. Chorus 2nd Verse: Together they make gases, And liquids like molasses, And all the solid masses, The Atoms Family Chorus 3rd Verse: Neutrons can be found, Where protons hang around; Electrons they surround The Atoms Family. Chorus Chorus: They are so small. (Snap, snap) They’re round like a ball. (Snap, snap) They make up the air. They’re everywhere. Can’t see them at all. (Snap, snap) ATOMS ARE MADE OF 3 MAIN PARTS PROTONS POSITIVE INSIDE THE NUCLEUS IDENTIFIES THE ATOM WHY??? Because it will never change NEUTRONS NO CHARGE INSIDE THE NUCLEUS ELECTRONS NEGATIVE CHARGE IN THE ELECTRON CLOUD OUTSIDE THE NUCLEUS Small – has almost no mass There are 2 main locations in an atom: 1. Nucleus (contains protons and neutrons) Heaviest part of an atom. So the mass number is the sum of the protons and neutrons. 2. Electron cloud (contains electrons) 1st energy level can hold 2 electrons. 2nd energy level can hold 8 electrons 3rd energy level can hold 8 electrons. WHERE DO THE SUBATOMIC PARTICLES GO????
