Covalent Bonding

Covalent Bonding. Bonding models for methane, CH 4 . Models are NOT reality. Each has its own strengths and limitations. CA Standards. Students know atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.

Recap Lewis Structures

Recap Lewis Structures. Arrange the atoms. Count the total number of valence electrons. Allocate two electrons between each pair of atoms which are assumed to be covalently bonded. Use remaining valence electrons to form lone pairs. Check if the central atom has an octet (or more).

Molecular structure and naming

Molecular structure and naming. Moving from Lewis dot to Structural formula. You have been using Lewis dot structures and molecular formulas Now we simplify it with structural formulas Structural formulas use symbols and bonds to show relative position of atoms. Figuring out number of bonds.

LEWIS DIAGRAMS

LEWIS DIAGRAMS. Ionic Compounds. Use arrows to represent the transfer of electrons. The final structure will contain ions. Octet-Rule Covalent Compounds. Simple covalent compounds such as CH 4 may be done by pairing electrons from different atoms. The pairing is shown with circles.

Resonance

Resonance. There are certain cases in which a single Lewis structure cannot correctly describe a molecule. Example : O 3 Experimental evidence shows each of the oxygen-oxygen bonds are identical. Actual structure is an average of the resonance structures. Polyatomic Ions
