• cation

• dogion

An ionic bond results due to the __________ attraction between 2 oppositely charged ions.

• delocalized
• weird
• electrostatic
• ionization

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 moving 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
