TRANSCRIPT
Notes:
1. Metals
2. Metalloids(semimetals)
3. Nonmetals
Metals are to the left of the semimetals.
1. Solid (except for Mercury which is the only liquid metal).
2. Lustrous (this means it is shiny)
3. Malleable (this means it is bendable or can be
flattened into a sheet)
4. Ductile (this means it can be shaped into
wires).
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.
6. High melting and boiling points.HOT HOT HOT!
What are the 6 properties of metals?
Nonmetals are to the right of the semimetals.
1. Solid, Gas, or Liquid(Bromine is the only liquid nonmetal)
2. Dull(this means it is NOT shiny).
3. Brittle (this means it crumbles into pieces)
4. Poor conductors of heat and electricity.
5. Low melting and boiling points.
What are the 5 properties of non-metals?
Most elements with a side touching thezig-zag line are semimetals exceptaluminum.
They are: B, Si, Ge, As, Sb, Te, Po, At. (Everything on the stair but Aluminum!)
1. They have properties of both metals
and non-metals.(some are shiny, some are dull, they
canbe brittle or malleable, etc).Example: Silicon is shiny but brittle.
2. They are semiconductors. (this means they conduct heat and
electricity,but not as well as metals and under certaincircumstances).Ex. Silicon works well as a microchip.
What are the 2 properties of semi-metals?
•Shown here in redred boxes.•Only 2 elements are liquids at room temperature: Mercury (Hg) and Bromine (Br)
•Hydrogen (H)•Helium (He)•Nitrogen (N)•Oxygen (O)•Fluorine (F)•Chlorine (Cl)•Neon (Ne)•Argon (Ar)•Krypton (Kr)•Xenon (Xe)•Radon (Ra)•Shown here in purplepurple boxes.
•Shown here in yellowyellow boxes.
•Everything else on the periodic table is a solid.
METALSMETALS
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.

1. Which arrow points to Metals?
Semimetals? Nonmetals?

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