Notes: Periodic Table Part 2 Sections of the Periodic Table
The Periodic Table
What are the 3 main sections on the periodic table? 1. Metals 2. Metalloids (semimetals) 3. Nonmetals
Where are metals located on the periodic table? Metals are to the left of the semimetals.
What are 6 properties of most metals? 1. Solid (except for Mercury which is the only liquid metal).
What are 6 properties of most metals? 2. Lustrous (this means it is shiny)
What are 6 properties of most metals? 3. Malleable (this means it is bendable or can be flattened into a sheet)
What are 6 properties of most metals? 4. Ductile (this means it can be shaped into wires).
What are 6 properties of most metals? 5. Good Conductors of heat and electricity. We cook with metal to transfer heat to our food. We use metals in wires to conduct electricity throughout our house.
What are 6 properties of most metals? 6. High melting and boiling points. HOT HOT!
Tell your partner… What are the 6 properties of metals?
Where are nonmetals located on the periodic table? Nonmetals are to the right of the semimetals.
What are the 5 properties of nonmetals? 1. Solid, Gas, or Liquid (Bromine is the only liquid nonmetal)
What are the 5 properties of nonmetals? 2. Dull(this means it is NOT shiny).
What are the 5 properties of nonmetals? 3. Brittle (this means it crumbles into pieces)
What are the 5 properties of nonmetals? 4. Poor conductors of heat and electricity.
What are the 5 properties of nonmetals? 5. Low melting and boiling points.
Tell your partner… What are the 5 properties of nonmetals?
Where are semimetals (metalloids) located on the periodic table? Most elements with a side touching the zig-zag line are semimetals except aluminum.
What are the Semi-Metals (metalloids)? They are: B, Si, Ge, As, Sb, Te, Po, At. (Everything on the stair but Aluminum!)
What are 2 properties of metalloids? 1. They have properties of both metals and non-metals. (some are shiny, some are dull, they can be brittle or malleable, etc). Example: Silicon is shiny but brittle.
What are 2 properties of metalloids? 2. They are semiconductors. (this means they conduct heat and electricity, but not as well as metals and under certain circumstances). Ex. Silicon works well as a microchip.
Tell your partner… What are the 2 properties of semimetals?
What are the Liquids on the periodic table? • Shown here in red boxes. • Only 2 elements are liquids at room temperature: Mercury (Hg) and Bromine (Br)
What are the Gases on the periodic table? • Hydrogen (H) • Helium (He) • Nitrogen (N) • Oxygen (O) • Fluorine (F) • Chlorine (Cl) • Neon (Ne) • Argon (Ar) • Krypton (Kr) • Xenon (Xe) • Shown here in purple boxes. • Radon (Ra)
What are the Solids on the periodic table? • Shown here in yellow boxes. • Everything else on the periodic table is a solid.
Label the metals, semimetals, and nonmetals on this periodic table.
METALS NONMETALS SEMIMETALS
OUTPUT Conclusion: Write at least 5 complete and complex sentences explaining the properties of metals, semimetals, and nonmetals. Be sure to include where these main sections are on the periodic table including the solids, liquids, and gases.

OUTPUT WE WILL USE YOUR COLORCODED PERIODIC TABLE TO ANSWER QUESTIONS 1 -11.
OUTPUT WE WILL USE YOUR COLORCODED PERIODIC TABLE TO ANSWER QUESTIONS 1 -11.
OUTPUT 1. Which arrow points to Metals? Semimetals? Nonmetals? C A B
OUTPUT 1. Which arrow points to Metals? Semimetals? Nonmetals? C: Non metals A: Metals B: Semimetals
OUTPUT 2. Is Germanium (32 protons) a metal, semi-metal or nonmetal?
OUTPUT 2. Germanium is a semi-metal because it touches the zig-zag line
OUTPUT 3. Is Aluminum (13 protons) a metal, semi-metal or nonmetal?
OUTPUT 3. Aluminum is a metal. It’s the only element touching the zig-zag line that is NOT a semi-metal
OUTPUT 4. Is Bromine (35 protons) a metal, semi-metal or nonmetal?
OUTPUT 4. Bromine is a nonmetal
OUTPUT 5. Name all 8 semi-metals
OUTPUT 5. Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Polonium, and Astatatine (they are all touching the zig-zag line
OUTPUT 6. Is Mercury a solid, liquid or gas at room temperature?
OUTPUT 6. Mercury is the only liquid metal element at room temperature
OUTPUT 7. What is the other liquid on the periodic table and is it a metal, semi-metal or nonmetal?
OUTPUT 7. Bromine is the other liquid and it is a nonmetal
OUTPUT 8. Is Iodine (53 protons) a solid, liquid or gas at room temperature?
OUTPUT 8. Iodine is solid at room temperature (you may be familiar with liquid ‘iodine’ at the doctor office. That is not pure iodine)
OUTPUT 9. Are all the elements in Group 18 or 8 A gases at room temperature?
OUTPUT 9. Yes, all the elements in Group 18 or 8 A are gases, and they are all inert (unreactive) gases
OUTPUT 10. List the 5 other gases that are not in the Group 18 gases.
OUTPUT 10. The other gases are Hydrogen, Nitrogen, Oxygen, Fluorine and Chlorine
OUTPUT 11. Are all the semi-metals also solid at room temperature?
OUTPUT 11. Yes, all the semi-metals are solid at room temperature.
OUTPUT WE WILL NOW USE YOUR BLUE PERIODIC TABLE TO ANSWER QUESTIONS 12 -19. YOU MAY NOT LOOK AT YOUR COLOR-CODED PERIODIC TABLE!
OUTPUT 12. Is Boron (5 protons) a metal, semi-metal or nonmetal?
OUTPUT 12. Boron is a semi-metal. I know this because it’s to the left/right of the zig-zag line
OUTPUT 13. Is Gallium (31 protons) a metal, semi-metal or nonmetal?
OUTPUT 13. Gallium is a metal. I know this because all metals are to the left of the semimetals
OUTPUT 14. List all 11 gases
OUTPUT 14. All gases are toward the right side of the periodic table except Hydrogen. The gases are: Hydrogen, Helium, Nitrogen, Oxygen, Fluorine, Chlorine, Neon, Argon, Krypton, Xenon and Radon
OUTPUT 15. What are the only 2 liquids at room temperature on the periodic table?
OUTPUT 15. Mercury and Bromine No trick to remember this, just memorize them!
OUTPUT 16. List the 5 nonmetals that are solid at room temperature
OUTPUT 16. Carbon, Phosphorus, Sulfur, Selenium, Iodine
OUTPUT 17. Where all nonmetals located (except for Hydrogen)?
OUTPUT 17. All nonmetals are to the right of the semi-metals, except for Hydrogen
OUTPUT 18. Which elements conduct heat and electricity the best: metals, nonmetals or metalloids?
OUTPUT 18. Metals conduct heat and electricity the best
OUTPUT 19. Which elements are brittle: metals, nonmetals or metalloids?
