Chapter 11.3, Problem 5RQ

Interpretation Introduction

Interpretation: The shapes and sizes of the s orbitals of the different energy levels of a hydrogen atom are to be compared.

Concept Introduction: The shape of an orbital depends on the movement of electrons inside it which is defined by the quantum numbers.

Answer to Problem 5RQ

The shape of s orbital of each energy level of the atom is similar which is spherical shape. The size of each orbital increases with increase in energy level.

Explanation of Solution

The shape of each s orbital is spherical because their angular momentum number is zero. The movement area of electrons will increase with increasing energy, so the size of orbital will also increase with increase in energy level.
