How many of the following sets of quantum numbers n,l,m I are allowed for the hydrogen...

Question

Question

Answer 1

Answer #1

for n=1

maximum value that l can take will be = n-1 = 0

also since m_l ranges from -l to +l, therefore m_l =0

hence the only set that is possible is 1,0,0

correct option is (e)
