Unit 4: Concept 3 Metallic Bonds

Metals are strong absorbers and reflectors of light.When light is shone on to the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light.

This process is responsible for which property of metals?

What is a metallic bond?

In metallic bonds, do metal atoms lose their valence electrons?

Do metallic bonds result in the formation of compounds?

What type of structures do metals like to form in metallic bonds?

How does the "Sea of Electrons" model explain the malleability of metals?

Melting point is the temperature at which a substance changes state from solid to liquid (melts).

Solubility is the ability of a substance to be dissolved in water.

Which of the following do you think is a result of the "Sea of Electrons" in metals?

Which types of energy can metals conduct?

What is a key characteristic of a metallic bond?
