1. rank the reactivity of the following elements from least reactive (4) to most reactive (1).

barium, __ gallium, boron, __ cesium

1. what is the ion charge of:

calcium ____ carbon ____
rubidium ____ radon ____
nitrogen ____ boron ____

Explanation:

Step1: Fill group details

Name of Group	Valence Electrons	Ionic Charge
B (Alkaline Earth Metals)	2	$+2$
C (Group 13)	3	$+3$
D (Group 14)	4	$\pm4$
E (Group 15)	5	$-3$
F (Group 16)	6	$-2$
G (Group 17, Halogens)	7	$-1$
H (Group 18, Noble Gases)	8 (2 for He)	$0$

Step2: Answer periodic table location questions

1. Left/center of the table.
2. Right side (except H).
3. Staircase line (B, Si, Ge, As, Sb, Te).
4. 1 valence electron, matches alkali metals.
5. Full valence shell, matches noble gases.

Step3: Answer group terminology questions

1. Group (or family).
2. Period.

Step4: Answer periodic trend questions

1. Increased reactivity (metals), decreased (nonmetals).
2. Decreased metallic character, increased nonmetallic.

Step5: Answer ion/element questions

1. a. Fluorine, b. Chlorine, c. Bromine
2. $+2$
3. $-3$
4. Carbon
5. Fluorine
6. Francium (or Cesium)

Step6: Rank reactivity

1. 3. Bromine, 2. Iodine, 4. Chlorine, 1. Fluorine
2. 1. Strontium, 2. Magnesium, 3. Calcium, 4. Beryllium
3. 3. Barium, 2. Gallium, 4. Boron, 1. Cesium

Step7: Find ionic charges

Calcium: $+2$, Carbon: $\pm4$, Rubidium: $+1$, Radon: $0$, Nitrogen: $-3$, Boron: $+3$

Answer:
