Why do solid ionic compounds not conduct electricity?

The ions are fixed and cannot move Their electrons are not free to move They contain no charged particles They contain only molecules

Why are metals malleable?

Their atoms are soft Their bonds are weak Their layers of ions can slide over one another They contain molecules that bend

Which of the following correctly describes the structure of poly(ethene)?

Ionic lattice of repeating ions Lattice of positive ions in a sea of electrons Long chains of covalently bonded atoms Simple molecules held by weak forces

Which particle is responsible for electrical conductivity in metals?

Delocalised electrons Ions Molecules Protons

What type of particles are present in a metallic lattice?

Metal atoms Molecules Neutral atoms Positive ions and free electrons
