Is this correct
Apologies for the mix-up in my previous response. Here are the correct matches:
1. Group 1A: b. +1
2. Group 2A: h. +2
3. Group 3A: c. +3
4. Group 4A: f. +4/-4
5. Group 5A: a. -3
6. Group 6A: e. -2
7. Group 7A: d. -1
8. Group 8A: g. 0
Please note that the answer for Group 5A has been corrected from -1 to -3, and the answer for Group 6A has been corrected from -2 to -2.
Here are the matches between the groups and the type of ions they form:
1. Group 1A: b. +1
2. Group 2A: h. +2
3. Group 3A: c. +3
4. Group 4A: g. 0
5. Group 5A: e. -1
6. Group 6A: f. +4/-4
7. Group 7A: d. -3
8. Group 8A: g. 0
To match the groups in Column A with the type of ions they form in Column B, we need to consider the group number and the common oxidation states of the elements in each group.
Column A:
1. Group 1A: Group 1A elements belong to the alkali metal group in the periodic table. They are highly reactive metals and tend to lose one electron to achieve a stable electron configuration. This means they typically form cations with a charge of +1. Therefore, the corresponding option in Column B is b. +1.
2. Group 2A: Group 2A elements belong to the alkaline earth metal group. Similar to Group 1A, they also tend to lose electrons to achieve stability. However, they lose two electrons, resulting in cations with a charge of +2. So, the corresponding option in Column B is h. +2.
3. Group 3A: Group 3A elements belong to the boron family. They can either lose three electrons to form a +3 cation or gain three electrons to form a -3 anion. However, the most common ion formed is the +3 cation. Therefore, the corresponding option in Column B is c. +3.
4. Group 4A: Group 4A elements belong to the carbon family. They have variable oxidation states, but their most common oxidation state is +4. So, the corresponding option in Column B is f. +4/-4. Note that the "-4" represents the formation of anions (such as in compounds like carbides).
5. Group 5A: Group 5A elements belong to the nitrogen family. They tend to gain three electrons to achieve stability, resulting in anions with a charge of -3. Therefore, the corresponding option in Column B is d. -3.
6. Group 6A: Group 6A elements belong to the chalcogens. They can either gain two electrons to form an anion with a charge of -2 or gain four electrons to form an anion with a charge of -2/-4. However, the most common ion formed is the -2 anion. So, the corresponding option in Column B is a. -2.
7. Group 7A: Group 7A elements belong to the halogens. They tend to gain one electron to achieve a stable electron configuration, resulting in anions with a charge of -1. Therefore, the corresponding option in Column B is e. -1.
8. Group 8A: Group 8A elements belong to the noble gases. They are chemically stable since their outer electron shells are already filled. Therefore, they do not readily form ions and have an oxidation state of 0. So, the corresponding option in Column B is g. 0.
Therefore, the matching pairs are as follows:
1. Group 1A - b. +1
2. Group 2A - h. +2
3. Group 3A - c. +3
4. Group 4A - f. +4/-4
5. Group 5A - d. -3
6. Group 6A - a. -2
7. Group 7A - e. -1
8. Group 8A - g. 0
