Overview

The structure of an atom is explained through the nature of light, atomic spectra, quantum theory, atomic models, quantum numbers, and electronic configuration. Atoms contain negatively charged electrons, positively charged protons, and electrically neutral neutrons. The arrangement of electrons aro

Key Concepts

White light can split into

White light can split into a continuous band of colours. A rainbow shows seven colours: violet, indigo, blue, green, yellow, orange, and red. Visible

Max Planck proposed that electromagnetic energy

Max Planck proposed that electromagnetic energy is absorbed or emitted in discrete packets. The energy of a packet is given by E = hν, where h = 6.626

Different elements emit light of characteristic

Different elements emit light of characteristic wavelengths when heated. These bright lines form line spectra. Sodium vapours produce yellow light in

Bohr proposed that electrons move

Bohr proposed that electrons move in stationary orbits of fixed energy around the nucleus. An electron absorbs energy when it moves to a higher orbit

Sommerfeld improved Bohr's model by adding

Sommerfeld improved Bohr's model by adding elliptical orbits. The first orbit remained circular, one elliptical orbit was added to the second orbit, a

Learning Objectives

  • Understand the electromagnetic nature of light and the meaning of spectrum
  • Relate wavelength, frequency, and the speed of light using c = νλ
  • Explain Planck's idea of discrete energy absorption and emission using E = hν
  • Describe line spectra and identify their use as fingerprints of elements
  • State Bohr's model of the hydrogen atom and its limitations
