Question

Hydrogen resembles the elements of groups:

Options

A
I-A, V-A and VIII-A
B
I-A, IV-A and VI-A
C
I-A, II-A and VII-A
D
I-A, IV-A and VII-A

Explanation

Hydrogen is unique in its periodic behavior but shows similarities to several groups. It resembles group I-A because it has one valence electron and can lose this electron to form a cation. It resembles group IV-A because it can share electrons, akin to the group IV-A elements with half-filled valence shells. Additionally, it resembles group VII-A in its ability to gain an electron and form an anion, similar to the halogens. The other options incorrectly associate hydrogen with groups where it does not demonstrate such chemical similarities.

This option suggests hydrogen resembles groups I-A, V-A, and VIII-A. While hydrogen is similar to group I-A because it can lose one electron, it does not exhibit significant resemblance to groups V-A or VIII-A in its chemical behavior.

Hydrogen shares characteristics with group I-A as it has one valence electron and can lose it to form a cation. It also resembles group IV-A due to its ability to share electrons, but it doesn't have significant resemblance to group VI-A.

This option implies hydrogen resembles groups I-A, II-A, and VII-A. While it resembles I-A and VII-A because it can gain an electron to form an anion, it does not closely resemble group II-A.

Hydrogen resembles group I-A due to its single valence electron and ability to form a cation. It resembles group IV-A through its half-filled valence shell and tendency to share electrons. It also resembles group VII-A because it can gain an electron to form an anion, making this the correct choice.
