1 I. Why Atoms Combine Chemical Formula Chemical Bond Stability

2 H2O A. Chemical Formula Shows: 1) elements in the compound
2) ratio of their atoms H2O 1 oxygen atom 2 hydrogen atoms

3 B. Chemical Bond Strong attractive force between atoms or ions in a molecule or compound. Formed by: transferring e- (losing or gaining) sharing e-

4 Ne C. Stability Octet Rule
most atoms form bonds in order to have 8 valence e- full outer energy level like the Noble Gases! Ne Stability is the driving force behind bond formation!

5 C. Stability Transferring e- Sharing e-

CHEMICAL BONDING Occurs when 2 or more atoms combine by sharing or transferring electrons. –Can be from the same element (O 2 ) or different elements (NaCl)

Covalent Bonds.

Covalent Bonds.
The rules to. The TWO basic rules  Opposites ATTRACT and likes REPEL  Nature moves in the direction of the least resistance (lowest energy)

PS.2b Compounds. Compounds are made of 2 or more kinds of atoms which combine in a specific ratio.

The Octet Rule. Happy atoms have a full outer energy level of electrons. They rarely combine with other elements. Nonreactivity is why they are called.
