Abstract: In general metals are able to emit a small number of secondary electrons. The electropositive elements have a smaller secondary emission with a primary electron energy of 100 volts or more than metals with a high work function. The opposite contention is often encountered in literature; it is pointed out that this is due to experimental errors (insufficient vacuum), consisting in the fact that the measurements are carried out on the compounds which have a much higher secondary electron emission. Several short statements of the facts observed are given, and these facts will be interpreted in further articles.
