A mixture of two or more metals is called:

• mixture
• solution
• compound
• alloy

What is the basis of a metallic bond?

• the attraction of neutral metal atoms.
• the attraction between protons and neutrons.
• the attraction between positive metal ions and interlocking electrons.
• the attraction between positive metal ions and free floating electrons.

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
