Here is the matching of the groups to the type of ions they form:
1. **Group 1A**: d. +1
2. **Group 2A**: f. +2
3. **Group 3A**: g. +3
4. **Group 4A**: b. +4/-4
5. **Group 5A**: h. -3
6. **Group 6A**: e. -2
7. **Group 7A**: a. -1
8. **Group 8A**: c. 0
This arrangement reflects the common ion charges for elements in these groups of the periodic table.
