Answer:
1. They travel in straight lines.
2. They are independent of the material composition of the cathode.
3. Applying electric field in the path of cathode ray deflects the ray towards positively charged plate. Hence cathode ray consists of negatively charged particles.
Explanation:
Most of the atom’s mass and its entire positive charge are confined in a small core, called nucleus. The positively charged particle is called proton.
Most of the volume of an atom is empty space.
The number of negatively charged electrons dispersed outside the nucleus is same as number of positively charge in the nucleus. It explains the overall electrical neutrality of an atom.
