Metal Atoms

• Most Atoms are Classified as Metals

• Metallic Qualities: Luster, Malleable, Ductile, Hardness, Conductivity (Heat and Electricity)

• Some are Magnetic (Iron, Cobalt, Nickel)

• You are made of many metal atoms (sodium, zinc, iron, potassium, magnesium, etc)

Multiple Choice

Metal atoms are found in our bodies.

• True

• False

Multiple Choice

Which metals are magnetic?

• iron

• cobalt

• nickel

• all of these

Property: Luster

• Metals are Usually Shiny

• Reflective Surface

Multiple Choice

What term means that a surface is shiny and reflective?

• malleable

• ductile

• luster

• conductor

Property: Malleable

• Metals are Bendable (Mallet)

• Don't Break Easily

Multiple Choice

Which term means that metals can bend?

• malleable

• ductile

• luster

• conductor

Property: Ductile

• Metals Can Be Made Into Wire (Duct - ConDUCTor)

• Because They Don't Break Easily

Multiple Choice

What term means that metals can be made into wire?

• malleable

• ductile

• luster

• conductor

Property: Hardness

• All But One Metal is Solid at Room Temperature

• Mercury is a Liquid at Room Temperature

• Different Metals Have Different Hardness (Strength)

Multiple Choice

All metals have the same hardness or strength.

• True

• False

Property: Conductor

• Metals easily allow heat to flow through them.

• Metals easily allow electricity to flow through them.

Multiple Select

Metals are good conductors of (choose 2)

• heat

• softness

• brittle

• electricity

Metal Electrons

• Electrons in metals move easily from atom to atom

• Metals have "loosey-goosey" electrons

• They easily give atoms away

• When they lose a negative electron, they have more positive protons than negative electrons in their atoms.

• When this happens, the metal atom has a positive electric charge (cation).

Multiple Choice

What would be the best description of the electrons of metal atoms?

• tight

• loosey-goosey

• both of these

• neither of these

Non-Metal Atoms

• Examples: Hydrogen, Oxygen, Carbon, Sulfur, Chlorine

• Electrons are bound tightly to the atom

• Electrons are "tight"

• Insulators - do NOT let heat and electricity travel easily through them

Multiple Choice

What would be the best description of electrons of non-metals?

• tight

• loosey-goosey

• both of these

• neither of these

Multiple Choice

Since human have metal atoms in their bodies (magnesium, potassium, iron, etc), would humans be good conductors of electricity?

• Yes

• No
