Lewis Dot Structures

Lewis Dot Structures. Quick Review. Molecular Structure & Bonding. A molecular structure, unlike a simple molecular formula, indicates the exact 3-D nature of the molecule. It indicates which atoms are bonded to which atoms, and the 3-D orientation of those atoms relative to each other.

Covalent Compounds

Covalent Compounds. Why do atoms bond?. When a + nucleus attracts electrons of another atom Or oppositely charged ions attract( ionic bonds-metals and nonmetals) We know the octet rule- atoms tend to gain or lose or share e - in order to acquire a full set of 8 valence e -. Properties.
