Metallic Bonds Alloys are the every-day metals that we encounter. They are a mixture of two or more types of metals. Alloys are generally stronger and less reactive than the pure metals that they are made from.
Metallic Bonds Most metals have only 1,2 or 3 valence electrons. This means that they always “give up” their electrons (similar to an ionic bond) When atoms give up electrons, the atom becomes positive.
Metallic Bonds In metallic bonds, the atoms come together Once the atoms are together, their valence electrons move around them creating a sea of negativity. The atoms release their specific electrons and allow them to flow around all of the atoms bonded together.
Metallic Bonds These metallic bonds are held together by the positive metal ions and the sea of negative electrons around them. The more valence electrons an atom can add to the “sea” the stronger the metal becomes.
Metallic Bonds Because these bonds are not formed through a rigid structure, metals have special properties: Malleability and Ductility Luster (shiny) Electrical conductivity Thermal (heat) conductivity
