What was discovered about electrons when changing the type of gas in a cathode ray tube?

The correct understanding regarding the behavior of electrons in a cathode ray tube is that the ray produced was indeed consistent regardless of the gas type used. This consistency indicates that the fundamental properties of electrons are intrinsic and do not depend on the external gas within the tube.

When different gases were used in the cathode ray tubes, researchers observed that the cathode rays (which are streams of electrons) exhibited the same characteristics. This led to the conclusion that electrons behave similarly irrespective of the type of gas present because they possess the same charge-to-mass ratio and other intrinsic properties.

This principle was crucial in affirming that electrons are a fundamental component of atoms, confirming their role in atomic structure, and demonstrating that they can be observed and studied under various conditions without altering their core characteristics. This foundational discovery contributed significantly to the development of atomic theory and our understanding of matter on a subatomic level.
