Hydrogen
Oxygen
Nitrogen
Water Vapor
Answer
Water vapor was the element used by Wilson in his cloud chamber experiments. The cloud chamber is a device that allows the visualization of the tracks of charged particles as they pass through a supersaturated vapor. When a charged particle passes through the vapor, it ionizes the molecules, creating a trail of ions.
