half life, fusion and fission

Question 1

What is half-life

Answer 1

Half-life is the amount of time taken for half of an amount radioactive material to decay. Usually, any amount of a certain isotope takes the same amount of time to decay.

Question 2

Is half-life accurate

Answer 2

Half-life is just an average of many experiments taken of how much time half an amount of an isotope takes to decay. It won’t always be exsactly 3.278 secs but it will be close to that number

Question 3

examples of half-life

Answer 3

For example, if there were 100g of Cf-251 in a sample at some time, after 800 years, there would be 50g of Cf-251 remaining. After another 800 years (1600 years total), there would only be 25g remaining. In 5700 years roughly half an amount of carbon will have decayed.

Question 4

What is fusion

Answer 4

Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles. These subatomic particles are released and create radiation.

Question 5

what is fission

Answer 5

Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei in the process releasing energy, often in the form of gamma photons.
