Answer 1

Here is the correct matching of the groups from Column A to the types of ions they form in Column B:

1. **Group 1A:**
**e. +1**
(Alkali metals, such as sodium and potassium, typically form +1 cations.)

2. **Group 2A:**
**g. +2**
(Alkaline earth metals, such as magnesium and calcium, typically form +2 cations.)

3. **Group 3A:**
**d. +3**
(Elements like aluminum typically form +3 cations.)

4. **Group 4A:**
**a. +4/-4**
(Elements like carbon can form covalent bonds and may exhibit +4 or -4 oxidation states.)

5. **Group 5A:**
**h. -3**
(Elements like nitrogen typically form -3 anions, such as nitride.)

6. **Group 6A:**
**f. -2**
(Elements like oxygen typically form -2 anions, such as oxide.)

7. **Group 7A:**
**b. -1**
(Halogens, such as chlorine and fluorine, typically form -1 anions.)

8. **Group 8A:**
**c. 0**
(Noble gases are typically non-reactive and exist in their elemental form with no charge.)

So, the complete matches are:
1. Group 1A - e. +1
2. Group 2A - g. +2
3. Group 3A - d. +3
4. Group 4A - a. +4/-4
5. Group 5A - h. -3
6. Group 6A - f. -2
7. Group 7A - b. -1
8. Group 8A - c. 0
