Why are metals malleable?
They are shiny
The electrons are held tightly within the lattice structure making it strong
The electrons are delocalized and able to move between the atoms
The electrons are shared between two metal ions and this holds the atoms together
Why do metallic compounds conduct electricity as solids?
core electrons are mobile, allowing electricity to flow through the metal
valence electrons are mobile, allowing electricity to flow through the metal
protons are mobile, allowing electricity to flow through the metal
the metal cations are mobile, allowing electricity to flow through the metal
Which of the following is TRUE about ionic compounds?
