gr11 chemical bonding lewis diagram bond polarity etc

When atoms react to form a chemical bond, their valence electrons are involved (electrons in the outermost highest main energy level) not core electrons. In 1900’s Gilbert Lewis came up with an idea, to represent the valence electrons of atoms. He also showed the electrons involved in the chemical bond between two atoms. He suggested that chemists use the system of dots to show valence electrons, called Lewis Dot Diagrams. In a Lewis diagram firstly, one dot is placed on each side of the element’s symbol until all four sides are occupied. Then the dots are doubled on each side until all valence electrons are used. The exact placement of the single dots is not important.
