Alpha particles are nuclei of helium, whereas beta particles are electrons.
Thus, Alpha particle ionised more gas molecule in the cloud chamber than beta particles, producing more alcohol and water.
Also, Alpha Particles are heavier than beta Particles----thus they are less deflected.
do you know what an alpha particle IS?
what are its physical properties?
Which property of alpha is opposite that property of a beta?
Which properties are a couple thousand times that of the beta?
Are you able to immerse this cloud chamber in any Fields?
