Answer 1

Explanation:

2)The nucleus makes up a tiny proportion of the space occupied by an atom, while the electrons make up the rest. According to quantum electrodynamics, the space is filled by an electron field around the nucleus which neutralizes its charge and fills the space defining the atom size.

1)Cathode rays also get deflected when these are subjected to a strong magnetic field. The electrons in the cathode rays would deflect toward the positively charged plates, and away from the negatively charged plates.
