Quick explanation

Describe how alpha (α), beta (β), and gamma (γ) particles are deflected in electric and magnetic fields

  • This point belongs to The three types of nuclear emission, especially The three types of nuclear emission outcomes.
  • You need to be able to describe how alpha (α), beta (β), and gamma (γ) particles are deflected in electric and magnetic fields.
  • The key ideas to know are Describe and Investigate.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Description

Deflection of Radiation

Alpha, beta, and gamma particles behave differently when placed in electric and magnetic fields. Alpha particles are positively charged, beta particles are negatively charged, and gamma rays are uncharged.

  1. a

    State the charge of alpha particles.

    Aim for approximately 1 distinct marking point.
