Chapter 5.1, Problem 4LC

Interpretation Introduction

Interpretation: The movement of electrons in an atom from one energy level to another needs to be explained.

Concept Introduction: An atom is composed of protons, neutrons, and electrons. Here, protons and neutrons are present in the nucleus of an atom and electrons are present in the orbitals around the nucleus of an atom. There are different energy levels in these orbitals and electrons can move from one energy level to another.

Explanation of Solution

In an atom, electrons are distributed in atomic orbitals. When heat is absorbed by an atom, the electron in an atom can jump from a lower energy level to a higher energy level. When energy is released, the electron comes back to the lower energy state. Here, energy is released in the form of a photon. Thus, the electron absorbs energy to jump from lower to higher energy levels and it releases energy to come back to the lower energy state.
