Atoms are amazing!12 Atoms are amazing!12 Presentation Transcript

  • ATOMS are AMAZING! 6 th grade Science Ada Christian School Mrs. Setsma
  • Why study atoms?
    • Atoms are the basis of Chemistry
    • Atoms make up EVERYTHING!
    • Studying atoms reveals the POWER and intimacy of God the Creator.
  • Atoms are Small!
    • In one cubic centimeter, there are an estimated 300,000,000,000,000,000,000 air molecules
    • Comparing the atom to the size of a golf ball is like comparing a golf ball to the size of EARTH!

  • Atoms contain mostly SPACE!
    • 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.

  • How are atoms connected to elements?
    • An element contains only one type of atom.
    • In other words, substances that consist of ALL of the same types of atoms are called elements.
  • How to Find information about Atoms on the Periodic Table?
    • Number of Electrons=Atomic Number
    • Number of Protons=Atomic Number
      • 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.
    • Number of Neutrons=Atomic mass-Atomic Number*
      • *Round to the nearest whole number BEFORE subtracting.
  • Example
    • Hydrogen
    • Atomic Number=1
    • Atomic Mass=1.0
    • Number of electrons=1; Number of protons=1
    • Number of Neutrons= 1-1=0
  • How to put Electrons on an Atom Model
    • 1 st ring=2 electrons
    • 2 nd ring=8 electrons
    • 3 rd ring=18 electrons
    • 4 th ring=18 electrons
