Description

Observa partículas alfa escapar de núcloes de átomos de Polonio, causando radiación chamada decaemento alfa. Ve como os tempos do decaemento aleatorio se relacionan coa vida media.

Obxectivos de Aprendizaxe

  • Explicar que é radiación alfa.
  • termos da súa aparición por efecto túnel.
  • Explicar o concepto de semiperiodo,incluído a súa natureza aleatoria.
  • Comezar a comprender o tipo de forzar que actúan para manter o núcleo atómico unido (forza nuclear forte) e as que traballan para provocar a súa desintegración (Coulomb, a forza eléctrica).
