Question

Statement 1: Hydrogen atom just needs one extra electron to achieve its duplet configuration.
Statement 2: Hydrogen atom has the tendency to acquire duplet configuration so that it can become stable.

• A. Statement 1 and 2 are correct, but statement 2 is not the correct reason for statement 1.
• B. Statement 1 and 2 are correct and statement 2 is the correct reason for statement 1.
• C. Statement 1 is correct and statement 2 is incorrect.
• D. Statement 2 is correct, but statement 1 is incorrect.

Answer 1

The correct option is B Statement 1 and 2 are correct and statement 2 is the correct reason for statement 1.

Hydrogen atom is made up of a single electron. As a result, it is made up of only one orbit. The first orbit can accommodate a maximum of two electrons.
In order to complete its duplet configuration, hydrogen atoms needs just one electron.
Duplet rule states that some elements can be stable with two electrons in their shell. Hydrogen and helium are special cases that do not follow the octet rule but the duplet rule. They are stable in a duplet state instead of an octet state.
Therefore, statement 1 and statement 2 is true and statement 2 is the correct explanation of statement 1.
