Metals have characteristic properties which make them very useful. These can be explained using appropriate models of metallic structure and bonding.
Which of the following are typical properties of metals?
High melting points, good conductors of electricity
Low melting points, good conductors of electricity
High melting points, poor conductors of electricity
What does the word 'malleable' mean?
Can be shaped
Can be drawn into wires
What does the word 'ductile' mean?
Can be drawn out into wires
What type of structure do metals have?
Which of the following is found in a metallic structure?
Positive metal ions and a sea of electrons
Negative metal ions and a sea of electrons
Positive ions and atoms only
What type of force creates a metallic bond?
Why are metals malleable?
They have weak bonds
Their layers can slide over each other
They have strong bonds
Why are metals good conductors of heat?
Their structure contains atoms that are free to move from place to place
Their structure contains positive ions that are free to move from place to place
Their structure contains electrons that are free to move
Why are metals hard?
Why do metals have high boiling points?
