Question

1. sort the groups names and elements with the correct group number by writing the appropriate letter(s) in each box

group 1a
group 2a
group b
group 7a
group 8a
a. krypton
b. magnesium
c. iron
d. transition elements
e. alkali metals
f. halogens
g. noble gases
h. alkaline earth metals

Explanation:

Step1: Recall Group 1A elements

Group 1A elements are Alkali Metals (E). So Group 1A box gets E.

Step2: Recall Group 2A elements

Group 2A elements are Alkaline Earth Metals (H) and elements like Magnesium (B) is in Group 2A. So Group 2A box gets B, H.

Step3: Recall Group B (Transition Metals)

Group B contains Transition Elements (D) and elements like Iron (C) is a transition metal. So Group B box gets C, D.

Step4: Recall Group 7A elements

Group 7A elements are Halogens (F). So Group 7A box gets F.

Step5: Recall Group 8A elements

Group 8A elements are Noble Gases (G) and elements like Krypton (A) is a noble gas. So Group 8A box gets A, G.

Answer:

• Group 1A: E (Alkali Metals)
• Group 2A: B (Magnesium), H (Alkaline Earth Metals)
• Group B: C (Iron), D (Transition Elements)
• Group 7A: F (Halogens)
• Group 8A: A (Krypton), G (Noble Gases)
