properties and structure of metals
ionic + metallic bonding- properties of metals.
1- are malleable
2-conduct electricity + heat
3-are dense and are ductile
4- hve high boiling and melting points
5- are shiny(when polished)
6- are sonorous(make a noise when hit)
7- are solid at room temperature(except mercury)
properties and structure of metals continued
structure of metals.
- ions are formed by the giving or receiving of electrons.
- ionic bonding is the electrostatic attraction of oppitley charged ions. the attraction acts in all directions and it is this attraction that is called the ionic bond.
- the attraction results in a giant structure arrangement called an ionic lattice.
there are 3 types of strong bonds in metals.
- ionic- electrons are transferred from metal atoms to non-metal atoms
-covalent-electrons are shared between atoms
-the outer electrons surrounding the atoms can easily move from one atom to the next. the outer electrons form what is called a 'sea' of free electrons surrounding positively charged metal ions.
