ChemistryStructure of AtomJEE Main 2022

Consider the following statements : (A) The principal quantum number 'n' is a positive integer with values of 'n' = 1, 2, 3, …. (B) The azimuthal quantum number 'l' for a given 'n' (principal quantum number) can have values as 'l' = 0, 1, 2, …n (C) Magnetic orbital quantum number 'ml' for a particular 'l' (azimuthal quantum number) has (2l + 1) values. are the two possible orientations of electron spin. (E) For l = 5, there will be a total of 9 orbital Which of the above statements are correct?

Answer: (3)

Solution

For a given n, l takes the values 0, 1, 2, …, (n − 1), not up to n, so (B) is wrong. For l = 5 the
