Answer :
Let's fill in the blanks of the table step-by-step using the provided information.
### 1. Determine the Number of Valence Electrons
- 2 A(2): According to the periodic table, elements in Group 2 have 2 valence electrons.
- 5 A (15): Similarly, elements in Group 15 typically have 5 valence electrons.
- 6 A (16): Elements in Group 16 usually have 6 valence electrons.
### 2. Determine Whether These Elements Tend to Lose or Gain Electrons (and How Many)
- 2 A(2): Given the properties of elements in Group 2, they tend to lose 2 electrons.
- 3 A (13): Elements in this group tend to lose 3 electrons.
- 5 A (15): Elements in this group tend to gain 3 electrons.
- 6 A (16): Elements in this group usually gain 2 electrons to achieve a stable electron configuration.
### 3. Determine the Ionic Charge
- 2 A(2): The ionic charge for Group 2 elements is +2, as they lose 2 electrons.
- 3 A (13): The ionic charge for Group 13 elements is typically +3.
- 5 A (15): When Group 15 elements gain electrons, they typically have an ionic charge of -3.
- 6 A (16): With the gain of 2 electrons, Group 16 elements usually have an ionic charge of -2.
Finally, we incorporate all of these details into the table:
[tex]\[ \begin{array}{|c|c|c|c|c|} \hline \text{Group} & \text{Example Element} & \# \text{ of Valence Electrons} & \text{Do these elements tend to lose or gain electrons? How many? (U2L.11)} & \text{Ionic charge (U2L11)} \\ \hline 1\ \text{A (1)} & \text{Fr} & 1 & \text{Lose 1} & +1 \\ \hline 2\ \text{A(2)} & \text{I} & 2 & \text{Lose 2} & +2 \\ \hline 3\ \text{A (13)} & \text{B} & 3 & \text{Lose 3} & +3 \\ \hline 4\ \text{A (14)} & & 4 & \text{Gain or Lose} & +1-4 \\ \hline 5\ \text{A (15)} & \text{N} & 5 & \text{Gain 3} & -3 \\ \hline 6\ \text{A(16)} & & 6 & \text{Gain 2} & -2 \\ \hline \end{array} \][/tex]
This completes our table with detailed filling for each missing data point.
