Question

Which of the following are possible values of n, I and m for an atom having maximum value of $ m=+2 $ ?

• A. $ n=4,1=3,\text{ }m=+2 $
• B. $ n=3,l=2,\text{ }m=-2 $
• C. $ n=3,l=3,\text{ }m=+2 $
• D. $ n=4,l=3,m=-2 $

Answer 1

Answer: (B)

If $ m=+2,l=2 $ [ $ \because $ $ m=-l $ to $ +l $ ] and $ l=n-1 $ $ 2=n-1 $ $ \therefore $ $ n=3 $ Hence, when $ n=3, $ $ l=2 $ , the maximum value of m is $ +2 $ .
