STANDARD Chemistry Ionization Energy Assertion Reason Question
Read the following statement and explanation and answer as per the options given below ; Assertion : The first ionization energy of Be is greater than that of B Reason : 2p-orbital is lower in energy than 2s
If both assertion and reason are Correct, and reason is the Correct explanation of the assertion
If both assertion and reason are Correct, but reason is Not the Correct explanation of the assertion
If assertion is Correct, but reason is Incorrect
If assertion is Incorrect, but reason is Correct.
Correct Answer
Detailed Explanation
The first ionization energy of Be is greater than that of B because Be has a completely filled 2s orbital, which is more stable than the partially filled 2p orbital of B, making it harder to remove an electron from Be.
