What is a metallic bond?
The electrostatic attraction between a lattice of positive metal ions and delocalised electrons.
The electrostatic attraction between protons and neutrons.
The electrostatic attraction between a lattice of positive metal ions and interlocking electrons.
What does malleable mean?
Able to be shaped.
Will break easily.
Can be used for wire.
Is shiny.
Why are alloys generally used to make everyday objects?
Alloys are often stronger and less reactive than pure metals.
Alloys have higher melting point than pure metals.
Alloys have ionic bonds instead of metallic bonds.
Why are metals malleable?
The disordered layers of metal ions in the lattice can slide over each other.
The electrons are delocalised and can move through the lattice.
The ordered layers of non-metal atoms in the lattice can slide over each other.
