Some properties of metals you need to learn!
Important point- Movement of electrons is needed for electricity to flow.
What gives metals these properties?Its their sturcture!
Why are metals Malleable?
The layers of positive ions in a metal can slide over each other, if a large force is applied to a piece of metal. The ions are held together by the sea of electrons, so the metal spreads out instead of breaking. It is malleable.
Metallic bonding
• Metal atoms form a giant lattice similar to ionic compounds.
• The outermost electrons on each metal are free to move throughout the structure and form a “sea of electrons”.
• Having released electrons into this “sea” the metal atoms are left with a + charge.
• The moving electrons allow for good heat and electrical conductivity
Metallic bonding is the attraction of + metal ions for the “sea of
delocalised electrons.”
