NEETChemistryStructure of Atom
The wave function, ψ n , l , m l is a mathematical function whose value depends upon spherical polar coordinates r , θ , ϕ of the electron and characterized by the quantum numbers n , l and m l . Here r is the distance from the nucleus, θ is colatitude and ϕ is azimuth. In the mathematical functions given in the Table, Z is the atomic number and a o is Bohr radius Column 1 Column 2 Column 3 (I) 1 s orbital (i) ψ n ,
Options
- A( III ) ( iii ) ( P )
- B( I ) ( ii ) ( S )
- C( IV ) ( iv ) ( R )
- D( II ) ( ii ) ( P )
Correct answer
D. ( II ) ( ii ) ( P )
Step-by-step solution
A IV iv R ⇒ incorrect, because, d z 2 has no nodal plane. B II ii P ⇒ correct, because 2 s orbital has 1 radial node. C III iii P ⇒ incorrect, because probability density for 2 p at nucleus is zero. D I ii S ⇒ incorrect, because 1 s orbital has no radial node.
