Question: Contrast Ionic vs. Covalent Bonds vs Metallic Bond

Answer: Ionic = transfer of electrons, and a chemical bond resulting from the attraction between positive and negative ions
Covalent= sharing electrons, no ion formation
Metallic = delocalize

==================================================

Question: What are the terms for positive and negative ions?

Answer: cations = positive (+)
anion = negative (-)

==================================================

Question: What is the octet rule?

Answer: main group elements gain or lose electrons to achieve a stable noble gases configuration (8 valence electrons, full s and p)

==================================================

Question: isoelectronic

Answer: having the same number of elections

==================================================

Question: Explain why noble gases are not likely to form chemical bonds.

Answer: Because they already have an electron configuration with a full, stable outer energy level.

==================================================

Question: Compare and contrast cations and anions.

Answer: Cations are formed from the loss of electrons and have a positive charge.
Anions are formed from the gain of electrons and have a negative charge.

==================================================

Question: Intramolecular Forces

Answer: Intromolecular: (forces between molecules)
- weaker than ionic or metallic bonds = molecules separate easier and have lower BP and MP. No ions present or mobile electrons = they are nonconductive of electricity.

Intermolecular:
- strength of network between the nonmetal atoms = very strong structure
