How many nodal surfaces through the nucleus (planar nodes) are associated with each of the following orbitals? (a) 2s (b) 5d (c) 5f

(a)

Interpretation Introduction

Interpretation: The number of nodal surfaces passing through the nucleus of 2s orbitals has to be identified.

Concept introduction:

Nodal surfaces: the surface which passing through nucleus where there is zero chance of finding electrons.

The values of l (azimuthal quantum number) when the principal quantum number is n are from 0 to (n1). Each value of l indicates subshell and for l=0,2 and 3 represents s, d and f subshells.

Explanation

Each value of l indicates subshell. For s subshells, l=0.

The s subshell has spherical shape and do

(b)

Interpretation Introduction

Interpretation: The number of nodal surfaces passing through the nucleus of 5d orbitals has to be identified.

Concept introduction:

Nodal surfaces: the surface which passing through nucleus where there is zero chance of finding electrons.

The values of l (azimuthal quantum number) when the principal quantum number is n are from 0 to (n1). Each value of l indicates subshell and for l=0,2 and 3 represents s, d and f subshells.

(c)

Interpretation Introduction

Interpretation: The number of nodal surfaces passing through the nucleus of 5f orbitals is to be identified.

Concept introduction:

Nodal surfaces: the surface which passing through nucleus where there is zero chance of finding electrons.
