Atoms are amazing!12

  1. 1. ATOMS are AMAZING! 6 th grade Science Ada Christian School Mrs. Setsma
  2. 2. Why study atoms? <ul><li>Atoms are the basis of Chemistry </li></ul><ul><li>Atoms make up EVERYTHING! </li></ul><ul><li>Studying atoms reveals the POWER and intimacy of God the Creator. </li></ul>
  3. 3. Atoms are Small! <ul><li>In one cubic centimeter, there are an estimated 300,000,000,000,000,000,000 air molecules </li></ul><ul><li>Comparing the atom to the size of a golf ball is like comparing a golf ball to the size of EARTH! </li></ul>
  4. 4. Atoms contain mostly SPACE! <ul><li>If you placed a bread crumb in the center of a large football stadium, the crumb would represent the atom ’ s nucleus (which has almost ALL the mass of the atom). The stadium ’ s top row seats would represent the outermost electrons. </li></ul>
  5. 5. How are atoms connected to elements? <ul><li>An element contains only one type of atom. </li></ul><ul><li>In other words, substances that consist of ALL of the same types of atoms are called elements. </li></ul>
  6. 6. How to Find information about Atoms on the Periodic Table? <ul><li>Number of Electrons=Atomic Number </li></ul><ul><li>Number of Protons=Atomic Number </li></ul><ul><ul><li>In order for the atom to be neutral, the number of electrons equals the number of protons. For now, we want to “ create ” neutral atoms. </li></ul></ul><ul><li>Number of Neutrons=Atomic mass-Atomic Number* </li></ul><ul><ul><li>*Round to the nearest whole number BEFORE subtracting. </li></ul></ul>
  7. 7. Example <ul><li>Hydrogen </li></ul><ul><li>Atomic Number=1 </li></ul><ul><li>Atomic Mass=1.0 </li></ul><ul><li>Number of electrons=1; Number of protons=1 </li></ul><ul><li>Number of Neutrons= 1-1=0 </li></ul>
  8. 8. How to put Electrons on an Atom Model <ul><li>1 st ring=2 electrons </li></ul><ul><li>2 nd ring=8 electrons </li></ul><ul><li>3 rd ring=18 electrons </li></ul><ul><li>4 th ring=18 electrons </li></ul>
