Metallic Bonding Flashcards
What is a metallic bond
The strong electrostatic force of attraction between positive metal ions and the negative sea of delocalised electrons
How are atoms arranged in metallic bonding
Giant lattice of closely packed atoms in a regular pattern
What are delocalised electrons
Bonding electrons which are not fixed in a bond between two atoms but rather are free to move and are shared by many atoms
Why do metals have high melting and boiling points
-consist of closely packed atoms with strong forces of electrostatic attraction between positive ions and negative delocalised electrons which requires a lot of energy to overcome and to move the positive ions away from their positions in the giant lattice
Why do metals have high densities
Atoms are closely packed with as little space between them as possible
Why are metals good thermal conductors
When metal is heated energy is transferred to electrons which move around faster and conduct the energy rapidly to other parts of the metal
Why are metals good electrical conductors
Delocalised electrons free to move through structure and carry electric charge
Why are metals malleable
Metallic bonds are strong but not directional as electrons can attract any of the positive ions meaning when a force is applied to the metal the layers of atoms can Slide Over each other(called slip)
