Presentation Transcript

  1. Metallic bond properties High melting and boiling points To cause metals to melt, enough energy has to be added to overpower the sea of electrons which holds the island of cations together and allow them to move. Malleable and ductile Much like moving parts of an island around, it is possible to move the cations around in various different shapes. Whichever shape you create, the sea of electrons will continue to surround the nuclei and hold them in place.

  2. Metallic bond properties • Good conductors of heat and electricity • In order to have electricity, you need moving electrons and there is no other model than through metallic bonds that allows for the movement of electrons. • Shiny • Light tends to bounce off of the sea of electrons quite nicely thereby making metals shiny.
