1a. Na1+
1b. F1-
1c. Ga3+
1d. O2-
1e. Ne0
1f. Al3+
2. Electrons in highest energy level (for s & p block elements they are also farthest away from nucleus)
It is important since these electrons are ones that move
3a. Ionic bond (really just a bunch of ions held together via CF)
3b. High EN (i.e.high CF) element with low EN (i.e. low CF)
4. Oxygen since it has a high CF to its valence electrons so atom wants to bring electrons toward it.
5. Ion
6. releases or give away
7. Metals are good conductors of electricity and heat and are malleable . Non-metals are not good conductor of electricity nor heat and are brittle.
8a. Fluorine valence electrons are more tightly held (high CF) than Chlorine's since the valence electrons are in a lower energy level.
8b. Fluorine valence electrons are more tightly held (high CF) than Oxygen atoms since Fluorine has a higher nuclear charge.
9. In a metallic bond there is a "sea" of free flowing electrons between the cations so that electrons are always between cations and electrons from electricity can move thru sea easily.
10a. False, 8 electrons
10b. True
10c. False
10d. False, 5ve-
11a. Mg
11b. O
11c. O
11d. Cl
12a. Fe, Ag
12b. F, Cl, Br, I, or At
12c .Li, Na, K, Rb, Cs, or Fr
12d. He, Ne, Ar, Kr, Xe, Rn
13. False
