Half life + some rando thingies notes chem t2

half life-

the time required for one half of the nuclei of a radioisotope to decay

forwards (draw it)

Transmutation reactions

atom of one element → atom of another

there are two types

Type 1:

radioactive decay- alpha betta, occurs naturally

Type 2:

nuclear bombardment- particles bombard a nucleus, not natural

A elements after U (bigger than 92)

are man made in nuclear reactor/accelerator

Nuclear fission

• the splitting of a nucleus

• Uraniums 235, and Plutonium 239 are the only fissionable isotopes

• when you fission (?) them there is a nuclear chain reaction

¹₀N+²²⁵₉₂U=

How do nuclear reactors work

1. fuel rods get hot and expland

2. gas is hotter than steam

3. this HOT water goes into a tube in another container 

4. this new container is filled with water that is heated into steam

5. the steam goes into a turbine and spins it creating energy

6. steam goes down into a new container and is cooled back into water

Label

pink- fuel rod uranium or plutonium

orange- hot water

blue- freezing water

yellow- steam → energy → water
