Well i named this thread group suggesting because i need help, i got an idea but i dont have any elements in mind. I was experimenting with fusion and came to an idea.

Well, that element should have Beta decay which means it should decay into electrons, we already have elements that decay into photons and two what decay into neutrons.

Uses: this kind of elements would have uses in nuclear reactors as well as fusion reactors because, Plutonium, creates pressure, heat and neutrons, and other element would produce electrons which leads into creating hydrogen and then on to fusion.

Feel free to suggest, modify my idea and correct me if i am wrong in any part.

EDIT: It would also be useful in creating two types of bombs.
