Metallic Bonding

Metallic bonds form because metals

• "want" to give up valence electrons

• always share valence electrons

• have many valence electrons

• always gain valence electrons

In metallic bonds, the force of attraction is between

• positive and negative ions

• cations and electrons

• two different metals

• neutrons and electrons

Metals are used to make electric wires because metals (choose all that apply)

• are ductile

• are shiny

• have free moving electrons

• form a lattice

How does a metallic lattice differ from an ionic crystal?

• A metallic lattice is less flexible

• A metallic lattice can change shape without breaking

• A metallic lattice shatters when struck

An alloy of iron and carbon is

• more likely to rust than pure iron

• weaker than pure iron

• a mixture of two METALS

• known as steel

True or False: A metallic bond may form between a metal and any other element
