Comment séparer les isotopes ?

Pour les quantités pondérables, notamment en vue d'applications militaires ou de production d'énergie, les deux procédés couramment utilisés sont l'ultracentrifugation et la diffusion gazeuse pour l'enrichissement de l'uranium.

Quand Dit-on que 2 atomes sont isotopes ?

Comprendre les isotopes. Les nucléides d'un élément qui ont le même nombre de protons mais un nombre différent de neutrons sont appelés des isotopes de cet élément.
. Il s'agit de variantes du même élément de base.

Comment calculer des isotopes ?

Les isotopes d'un même élément ont des propriétés chimiques identiques mais des propriétés physiques différentes (stables ou radioactifs notamment).
. Par exemple, l'hydrogène a trois isotopes : De son côté, l'uranium a 17 isotopes, tous radioactifs.
. Ils poss?nt tous 92 protons mais ils ont entre 125 et 150 neutrons.
