Question

1. refer to the periodic table below and answer the questions that follow. which letters represent alkali metals? which letters represent good conductors? which letters represent halogens? which letters represent elements with 1 valence electron? which letter represents an element with similar properties as letter a? which letters represent alkaline earth metals? which letters represent transition metals?

Explanation:

Step1: Recall periodic - table groups

Alkali metals are in Group 1, alkaline - earth metals in Group 2, halogens in Group 17, transition metals in the d - block. Good conductors are metals. Elements with 1 valence electron are in Group 1.

Step2: Identify alkali metals

Alkali metals are in the first column of the periodic table (excluding hydrogen). In the given table, the letter representing alkali metals is A.

Step3: Identify good conductors

Metals are good conductors. Transition metals (in the d - block) are good conductors. The letter representing transition metals is H.

Step4: Identify alkaline - earth metals

Alkaline - earth metals are in the second column of the periodic table. The letter representing alkaline - earth metals is D.

Step5: Identify elements with 1 valence electron

Elements in Group 1 have 1 valence electron. The letter representing elements with 1 valence electron is A.

Step6: Identify elements with similar properties as A

Elements in the same group as A (Group 1) have similar properties. The letter representing an element with similar properties as A is C (assuming it's in the same group).

Step7: Identify halogens

Halogens are in Group 17. The letter representing halogens is G.

Answer:

Alkali metals: A
Good conductors: H
Alkaline - earth metals: D
Elements with 1 valence electron: A
Element with similar properties as A: C
Halogens: G
Transition metals: H
