CHXI02:STRUCTURE OF ATOM

307288 Assertion :
Electronic configuration of an element is \(1 \mathrm{~s}^{2} 2 \mathrm{~s}^{1}\).
Reason :
In \(2 \mathrm{~s}, 2\) signifies the maximum capacity of S-subshell.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
