Answer 1

1. The electrons are extremely small and nobody has determined their size but the radius of the electron was calculated to be equal to $2.8179\times {10}^{-15}m$
2. Electrons sometimes act as a ball, sometimes like a wave, and sometimes like a cloud.
3. It is difficult to decide where the edges of the electron are to determine the size.
