1. Mixtures Solutions ATOM  Tiniest building block of all matter. Elements Compounds

2. ELEMENT  Elements  * the substance * NOTE: A substance made of only one type of atom is called a(n) ________________. Made of only one type of particle Each has unique characteristic properties (such as density and melting point) 3 types: metals, non-metals and metalloids Can be chemically bonded together to form compounds Pure substance; can’t be separated into simpler substances element

3. Periodic Table of Elements  A chart that displays the elements in order of atomic number Shows information about protons, electrons, density, phase, etc. “Periodic”  shows a repeating pattern

6. Carbon has ____ protons and electrons per atom! Nitrogen has ____ per atom! Chemical Symbols 6 C Carbon 12.011 7 N Nitrogen 14.007 atomic number element atomic mass chemical symbol 6 7 Atomic number = # of ___________ and the # of ____________ Atomic mass = # of __________________________ Atomic mass – atomic number = # of _______________ How many neutrons does carbon have? protons protons + neutrons 12 – 6 = 6 neutrons electrons

7. Categories of Elements * Elements are classified into groups * based on their shared properties METALS: METALLOIDS: NONMETALS: Shiny, malleable, good conductors Semi-conductors; properties of both metals and non-metals Dull, brittle, non-malleable, poor conductors (can be solid, liquid or gas)

8. Metal, Metalloid, or Nonmetal? Calcium  metal

9. Metal, Metalloid, or Nonmetal? Argon  nonmetal (gas)

10. Metal, Metalloid, or Nonmetal? Manganese  metal

11. Metal, Metalloid, or Nonmetal? Antimony  metalloid

12. Metal, Metalloid, or Nonmetal? Silicon  metalloid

13. Metal, Metalloid, or Nonmetal? Bromine  nonmetal (liquid)

14. Metal, Metalloid, or Nonmetal? Gold  metal

15. Metal, Metalloid, or Nonmetal? Mercury  metal (liquid)
