WebIn alpha decay, an alpha particle is ejected from an unstable nucleus, so here's our unstable nucleus, uranium-238. An alpha particle has the same composition as a helium nucleus. We saw the helium nucleus in the previous video. There are two protons in the helium nucleus and two neutrons. WebAn atom of bismuth has 83 protons in its nucleus. Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a white, lustrous, brittle metal with a pinkish tinge. The metal is slowly attacked by oxygen and moisture but not easily corroded by acids. It tarnishes upon exposure to air, but the resulting film is non-adherent and can be …
