Metals and Non-Metals

Metals

Sodium

Mercury

Non-Metals

Property #1: State of Matter

•PREDICT

Property #1: State of Matter

• Metals are solids at room temperature (22 deg C)

• Nonmetals can be solids, liquids, or gases at RT

Property #2: Shiny or Dull?

•PREDICT

Property #2: Shiny or Dull?

• Metals are shiny, nonmetals are dull

Property #3: Malleability and Ductility

• Metals are malleable and ductile

• Nonmetals are brittle

• Brittle: easy to break

• Malleable: can be bent

• Ductile: can be stretched

Property #3: Malleability and Ductility

• PREDICT

Property #4: Conductivity

• PREDICT

Property #4: Conductivity

• Conductivity: how well it conducts electricity

• Metals conduct electricity

• Nonmetals don’t….

Bad Idea

Property #5: Thermal Conductivity

• PREDICT

Property #5: Thermal Conductivity

• Thermal (heat) conductivity: how well heat flows through it

• Metals conduct heat

• Nonmetals don’t…

Property #6: Melting Point

• PREDICT

Property #6: Melting Point

• Melting point: The temperature that an element melts at

• Metals have high melting points• Think of your pots and pans

• Nonmetals have low melting points• This is why they can be liquid or gas at room temperature

Property #7: Does it react with Acids?

• PREDICT

Property #7: Does it react with Acids?

• Metals react with acids

• Nonmetals do not react with acids

Metalloids/Semi-metals

• Metalloids share properties of metals and non-metals

Metalloids/Semi-metals

• Metalloids share properties of metals and non-metals

• EX: The metalloid Si is shiny like metals but brittle like non-metals

Noble Gases

• Most elements like to bond (stick to) themselves or other elements• EX: water, oxygen, chlorine gas

Noble Gases

• Most elements like to bond (stick to) themselves or other elements• EX: water, oxygen, chlorine gas

• NOBLE GASES don’t bond with other atoms because they have a full valence shell!!!• They are always found as single atoms

• EX: balloons are filled with He atoms
