Which of the following is the outermost shell for elements of the 2nd period?
K-shell
L-shell
M-shell
N-shell

Academic Chemistry NCERT Class 10

Correct answer: (b) L shell

Explanation: L is the valence shell for elements of the second period of the modern periodic table as the period number is decided by the number of valence shells.

For this question, two statements are given-one labelled Assertion (A) and the other labelled Reason (R) :Assertion (A): To have 2 or 8 electrons in the outermost shell of an atom is always considered to be the most stable electron arrangement of atoms.Reason (R): Though electrons in the outermost shell always impart stability to an atom, but 2 electrons in the outermost shell of an atom impart stability only when the outermost shell is the first shell (K shell), and no other shells are present in the atomSelect the correct answer to the above question from the options given below:Both A and R are true, and R is the correct explanation of the assertion Both A and R are true, but R is not the correct explanation of the assertion. A true but R is false.A is false but is true.
