- Exercice: Radio-10
Estimer le diamètre des noyaux suivants:
- 3H
- 40K
- 235U
Hinweis: Le rayon est calculé avec r = 1.2·10-15·A(1/3) (résultat en mètres, où A est la nombre de masse)
Solution: - 3H: d = 2·r = 2·1.2·10-15·3(1/3) = 3.46·10-15 m
- 40K: d = 2·r = 2·1.2·10-15·40(1/3) = 8.21·10-15 m
- 235U: d = 2·r = 2·1.2·10-15·235(1/3) = 1.48·10-14 m
