After Alpha and Beta emissions, if there is any extra energy left, gamma rays are emmited
2 of 5
If an unstable nucleus with the mass 226 and the atomic number 88 emits one alpha particle, what would its mass and atomic number change to?
mass- 222 atomic number-86 as an alpha particle has a mass of 4 and atomic number of 2
3 of 5
why is a new element formed when a beta particle is emitted from an unstable nucleus?
as the isotope gains a proton (The unstable isotope looses an electron but gains a proton changing its atomic number by adding one ) and it has no mass so the mass does not change.
