Explanation:

Question 5

In the periodic table, Group 1 elements (excluding hydrogen) are called alkali metals. Halogens are Group 17, boron family is Group 13, and alkaline earth metals are Group 2. So the correct option is the one with "alkali metals".

Group 13 elements in the periodic table are known as the boron family (since boron is the first element in Group 13). Alkaline earth metals are Group 2, alkali metals are Group 1, and halogens are Group 17. So the correct option is the one with "boron family".

Answer:

C. alkali metals (assuming the options are labeled as A: halogens, B: boron family, C: alkali metals, D: alkaline earth metals; adjust labels as per actual but the text is "alkali metals")
