Question

Which orbital notation does not have spherical node ________.

• A. n=2 ; l=0
• B. n=2 ; l=1
• C. n = 3 ; l= 0
• D. n=3 ; l=1

Answer 1

Answer: (B)

n=2 ; l=1

The correct answer is B) n =2 and l =1n = prinicpal quantum numberL = azumithal quantum numberL= 0 for s orbitalL= 1 for p orbitalL= 2 for d orbital1) n =2 and l =1 represent 2p orbital and p orbital does not have spherical node.2) n =1 and l =0 represent 1s orbital and s orbital have spherical node.3) n =2and l =0 represent 2s orbital and s orbital have spherical node.4) n =3 and l =0 represent 3s orbital and s orbital have spherical node.
