Metallic Bonds

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.

At room temperature, most metals are

• liquid
• solid
• gas
• an alloy

What is the ability of a substance to be pulled into a thin wire?

• Malleability

• Ductility

• Conductivity

• Solubility

Why do metals conduct electricity?

• They are shiny

• The electrons are held tightly within the lattice

• The electrons are delocalized and able to move

• The electrons are shared between two metal ions

What are the valence electrons in metallic bonds attracted to?

• Positively charged ions inside of the metal

• Positively charged ions outside of the metal

• Negatively charged ions inside of the metal

• Negatively charged ions outside of the metal.
