A) \[n\]
B) \[2n\]
C) \[{{n}^{2}}\]
D) \[2{{n}^{2}}\]
Correct Answer: D
Solution :
Maximum number of electrons in a shell will principal quantum number \[n\]is given by \[2{{n}^{2}}.\] for e.g., if \[\underset{(first\,shell)}{\mathop{n=1}}\,,\]number of \[{{e}^{-}}=2\times {{1}^{2}}\] = 2 electrons if \[\underset{(second\,shell)}{\mathop{n=2}}\,,\]number of \[{{e}^{-}},=2\times {{2}^{2}}\] \[=8\]electrons
