Chapter 5, Problem 73A

Interpretation Introduction

Interpretation : The difference between an orbit in the Bohr model and an orbital in the quantum mechanical model of the atom is to be compared.

Concept Introduction : Bohr explained the orbits in his postulates for the hydrogen atom. The quantum mechanical model explains the wave functions of hydrogen atoms called as atomic orbitals.

Answer to Problem 73A

An orbit is a circular path where the electrons revolve around the nucleus in the Bohr model and an orbital is a place where the electrons are present in the quantum mechanical model.

Explanation of Solution

Bohr was the first to quantitatively explain the fundamental characteristics of the hydrogen atom's structure and its spectrum.

He made advantage of Planck's idea of energy quantization.

A theoretical field called quantum mechanics examines how small objects move when they exhibit both observable wave-like and particle-like features.

According to the Bohr model, an orbit is a particular circular path taken by an electron as it circles the nucleus. On the other hand, an orbital is an area of space where an electron is likely to be found.
