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:

\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}
