Bonding in Metals


Metals

Metals

  • Made up of closely packed cations

  • Not neutral atoms

  • Valence e- can move

    Recall: What type of ionization energy do metals have?

Low = tend to lose e-


Metallic bonding

Metallic Bonding

  • Free floating valence e- are attracted to (+) metal ions


Bonding in metals

  • Free floating valence e- explain metallic properties:

    • Good conductors

    • Malleable & Ductile

    • Luster


Crystalline structure

Crystalline Structure

  • Metal atoms are arranged in very compact & orderly patterns


Alloys

Alloys

  • Mixtures that contain a metal & one or more ‘other’ elements

  • Superior properties

  • Examples:

    Sterling Silver –

    Bronze –

    Steel –

    Titanium -

Silver & Copper

Copper & Tin

Iron, Carbon, Chromium, Nickel

Aluminum & Vanadium
