Question

Which of the following statements accurately describes the dual behavior of hydrogen as mentioned in the document?
Options
A Hydrogen only behaves like an alkali metal by losing its electron.
B Hydrogen only behaves like a halogen by gaining an electron.
C Hydrogen can behave like an alkali metal by losing an electron to form H<sup>+</sup>, and like a halogen by gaining an electron to form H<sup>-</sup>.
Correct Answer
D Hydrogen does not exhibit any behavior similar to alkali metals or halogens.
Correct Answer

Option C is the correct answer.

Detailed Explanation

According to the document on page 3, hydrogen's electronic configuration (1s1) allows it to behave like an alkali metal by losing its only electron to form a hydrogen ion (H+), and it can also behave like a halogen by gaining one electron to form a hydride ion (H-).

Hint

Consider hydrogen's electron configuration and how it can achieve a stable noble gas configuration by either losing or gaining one electron.
