Topic 4 Test Review Flashcards
This deck covers most, if not all, theory needed for the test. For practice refer to the worksheet on GC and make sure you go over the textbook in case I missed anything

Ionic Bonding
the electrostatic attraction between oppositely charged ions (metals+non-metals)
How are cations formed?
metals loosing their outer shell electrons (+)
How are anions formed?
non-metals gain enough electrons to complete outer shell (-)
Lattice Structure
ionic lattice is a strong alternating pattern of anions and cations.
Properties of Lattice Structure
Only conducts electricity when molten or dissolved. Low volatility (high melting point). Soluble in water.
Covalent Bonding
the attraction of two atoms to a shared pair of electrons (non-metals)
Single<–>Triple Bonds
(properties)
Longer—Shorter
Weaker—Stronger
Expanded Octet
Periods ≥ 3 (can have more than 8 electrons)
