The scientific knowledge was necessary for Schrödinger’s work is the discoverd of electron.
<h3>What is electron and how was it discovered?</h3>
Thomson carried out new experiments that led him to conclude that cathode rays were formed by particles that have a negative charge. Later, Thomson proved that these rays were deflected by applying an electric field. Thus, these particles were called electrons.
The discovery of the electron allowed Schrodinger to explain quantum models that are based on how electrons behave.
