Bonding
Objectives:1. I can estimate if a bond will be ionic or covalent 2. I can model an ionic and covalent bond.3. I can explain common properties of ionic and covalent substances.4. I can write ionic unit formulas and name ionic substances.5. I can write binary molecular formulas and name binary molecular substances.6. I can identify a substance as being an acid.7. I can write the unit formula and name acids.

CHEMICAL BONDS
compound a pure substance of 2 or more elements chemically bonded
the mutual attraction between nuclei and valence electron of different atoms
Atoms react in a way that will • make them more stable• full valence shell

Ionic Bond: a bond between
a metal (cation) and a nonmetal (anion) with opposite charges.
ꞏ a complete transfer of electrons (gained or lost)ꞏ characteristic of salts
