Bonding and LEDS

L.E.D.S: Lewis Dot Structure


Facts:
a.k.a Lewis Dot Diagrams, Electron Dot Diagram and Electron Dot Structures
Shows the bonding between atoms and electrons
named after Gilbert Newton Lewis


How To Do It

  • Determine the Valence Electrons


Something like this...
Red dots are the valence electrons.
















  • Electrons must be placed into the structure.
Something like this...












* Always follow the Octet Rule: atoms combined in such way the have 8 electrons giving them the same number of electrons as a noble gas.

  • Bonding pair is shared between two atoms. Transferring of electrons.
Something like this...



Multiple Bondings
Facts:
used when in need of more electrons from one element

Just like this...
The electrons of Magnesium was transferred to th two chlorine's.

Results:





Lets try some exercises
