Answer 1

Let's match the groups in Column A to the type of ions they form in Column B:

1. **Group 1A:** h. +1
- The alkali metals in Group 1A form +1 ions.

2. **Group 2A:** d. +2
- The alkaline earth metals in Group 2A form +2 ions.

3. **Group 3A:** b. +3
- Elements in Group 3A, such as aluminum, typically form +3 ions.

4. **Group 4A:** g. +4/-4
- Group 4A elements, like carbon and silicon, can form +4 or -4 ions, depending on the bonding.

5. **Group 5A:** f. -3
- Nitrogen and phosphorus from Group 5A commonly form -3 ions.

6. **Group 6A:** c. -2
- Elements in Group 6A, such as oxygen and sulfur, typically form -2 ions.

7. **Group 7A:** e. -1
- Halogens in Group 7A form -1 ions.

8. **Group 8A:** a. 0
- Noble gases in Group 8A are generally non-reactive and do not form ions, hence they have a charge of 0.

Putting it all together, the matches are:

1: h
2: d
3: b
4: g
5: f
6: c
7: e
8: a
