This primer provides a systematic and rigorous introduction to the spectra and electronic structure of atoms, beginning with the hydrogen atom, and following a logical progression through the alkali metals, and the helium atom, to atoms with many unpaired electrons. Emphasis is placed on the explanation of the observed spectra using elementary quantum theory.

"This is an excellent book, which should belong on every student's bookshelf." - Chemisch Weekblad

"It was a pleasure to see this short book arrive for review. With less than 100 well laid-out pages, it is not too daunting for undrgraduates. It is well written, with good explanations and a large number of clearly-drawn diagrams. It is also very down to earth ... an excellent little book with much to recommend it for introductory atomic physics courses ... I have no hesitation in recommending it for physics undergraduates." - Dr R.C. Thompson, Contemporary Physics, 1994, Volume 35, number 6
