To match the group to the type of ions they form, we need to understand the valence electrons of each group.
In general, group 1A elements lose one electron to form a +1 ion, group 2A elements lose two electrons to form a +2 ion, and group 3A elements lose three electrons to form a +3 ion. These ions are called cations because they have a positive charge.
On the other hand, group 5A elements gain three electrons to form a -3 ion, group 6A elements gain two electrons to form a -2 ion, and group 7A elements gain one electron to form a -1 ion. These ions are called anions because they have a negative charge.
Lastly, group 4A elements can either lose or gain four electrons to form a +4 ion or a -4 ion, respectively. They can form both cations and anions, depending on the specific element.
Now let's match the groups to the type of ions they form:
1. Group 1A: d. +1 (forms a +1 cation)
2. Group 2A: c. +2 (forms a +2 cation)
3. Group 3A: b. +3 (forms a +3 cation)
4. Group 4A: f. +4/-4 (can form either a +4 cation or a -4 anion)
5. Group 5A: g. -3 (forms a -3 anion)
6. Group 6A: h. -2 (forms a -2 anion)
7. Group 7A: e. -1 (forms a -1 anion)
8. Group 8A: a. 0 (does not readily form ions and remains neutral)
Remember that this is a general trend, and specific elements within each group may have exceptions to these trends.
