Question

Do you think lithium-7 and beryllium-7 esotopes formed from fusion well be stable?

Answer 1

As natural abundance of Deuterium and Tritium is very less, so formation of Beryllium stable isotope Beryllium-9 is very rare. Other isotopes are unstable and hence we have very less abundance of Beryllium





I hope so it may be help you

Answer 2

Lithium 7 is stable; Beryllium 7 is unstable.

Explanation:

All isotopes come from fusion. In order for an isotope to be stable, the synthetic process should mimic the natural fusion as much as possible. However, this is not accurate. Lithium 7 is stable and accounts for 92.58% of all the natural occurrence of this element.

But Beryllium 7 has always been unstable. It decays via electron capture into Lithium 7 and has a half life of 53.23 days.
