Transcript of Metallic Bonding

By Marc Skinner and Maisie Smith Metallic Bonding Metallic Bonding The metal ions and the electrons are oppositely charged and they are attracted to eachother, these from strong electrostatic forces called metallic bonds. In metals, the atoms lose their outer
electrons to form metal ions, the
delocalised electrons flow round
the metal ions Metals contain the following physical properties, They Conduct heat, They conduct electricity, they generally have high melting points and boiling points, They are also strong and malleable (able to be moved out of place without breaking) They also reflect light. Physical properties of metals Solid and liquid metals conduct electricity. The delocalised electrons are free to move in the solid lattice, these electrons can act as carriers in the conduction of heat and electricity. Conductivity Metals have high melting points because of the strength of the metallic bonds, the strength of the metallic bonds depends on some
main factors, these are: the number of delocalised electrons and the packing arrangement of the metal atoms. High melting and boiling points The delocalised electrons allow the metal atoms to roll over eachother when a stress is applied. Malleable The bonding in metallic elements is called metallic bonding and it is different to both ionic and covalent bonding The more delocalised electrons the stronger the bond
and the higher the melting and boiling point. The more closely packed electrons, the
stronger the bond and the higher
the melting point & Boiling
Point They look shiny, and photons of light do not penetrte far into
the surface of a metal, they are typically reflected or they bounce off the surface of the metal. Other Qualities of metals include.. A summary of different bonds of atoms. Atoms Bonding Song Here is a song with all of their names :) Bonding Happens with
