Radioactivity AT1 Science
What particles does Alpha decay consists of?
2 protons and 2 neutrions
What is Fusion?
When nuclei combine
What is radioactive half-life?
It is the time required for a radioactive material to reduce to half of its initial value/radioactivity.
What is Fission?
When nuclei break up
What are the effects of radiation?
It causes atoms in other substances to iodise, free radicals are very reactive and will try to bond with surrounding atoms due to radiation.
Can you predict the when one atom will decay? (radioactive decay)
No, but you can predict when many atoms will decay.
Can radiation cause damage to our DNA?
Yes
What are the similarities between fusion and fission?
They both make reactions that produce energy.
The order of from the strongest to weakest type of radiation.
Alpha, Beta, Gamma
True or false, Beta radiation consists of high speed electrons that are emitted by isotopes that have too many neutrons.
True
Can radioactivity be predicted?
Radioactivity is a random process, no.
What is a hypothesis?
A hypothesis is an educated guess where you guess what the outcome of something is with scientific information to back up your arguement/guess.
