Radiation Flashcards
1
Q
why are some nuclei unstable
A
imbalance in forces between particles in nucleus
2
Q
what happens when an unstable nuclei emits radiation and why
A
nuclear radiation to become more stable
3
Q
what happens when radiation occurs
A
radioactive decay - random process
takes some energy with it
This reduces the overall energy of the nucleus
This makes the nucleus more stable
4
Q
what is alpha radiation
A
same as a helium nucleus: his is because they consist of two neutrons and two protons
alpha least penetrating, and highest ionisation
