Radioactive Decay

HideShow resource information
What atoms are radioactive materials made up of?
Atoms with an unstable nuclei
1 of 5
How is gamma radiation caused?
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.
4 of 5
What is the mass and charge of Gamma ?
0 for both charge and mass
