MCQ
When $\beta $-particles are sent through a tin metal foil, most of them go straight through the foil as
  • A
    $\beta $-particles are much heavier than electrons
  • B
    $\beta $-particles are positively charged
  • Most part of the atom is empty space
  • D
    $\beta $-particles move with high velocity

Answer

Correct option: C.
Most part of the atom is empty space
c
Fast moving electrons are called $\beta$ - particles. They pass through tin metal foil because, most of the part of atom is empty, explained by Rutherford in his gold foil experiment
