Question

Statement 1 (S1): The electronic configuration of oxygen is 2, 7.
Statement 2 (S2): An oxygen atom gains two electrons to attain the nearest noble gas configuration.

• A. S1 is true but S2 is false
• B. Both S1 and S2 are false
• C. Both S1 and S2 are true
• D. S1 is false but S2 is true

Answer 1

The correct option is D S1 is false but S2 is true

The electronic configuration of oxygen is 2, 6 instead of 2, 7. It has 6 electrons in the outermost shell.
Hence, S1 is false.

Atoms gain stability by attaining the nearest noble gas configuration. Therefore, an oxygen atom gains two electrons to attain the nearest noble gas configuration.
Hence, S2 is true.
