Definition
Alpha Particle   weakest type of neclear radiation  
🗑
artificial transmutation   changing of 1 element into anohter by unnatural means; involves bombarding a nucleus w/ a high energy particles to cause change.  
🗑
gamma ray   high frequency electromagnet wave released during gamma decay.  
🗑
beta particle   electron created in the nucleus of an atomo, released during beta decay.  
🗑
binding energy   energy associated with the strong nuclear force that holds atomic nucleus together, related to stability of a nucleus.  
🗑
decay series   sequence of steps by which a radioactive nucleus decays into a nonradioactive nucleus.  
🗑
half life   amount of time it takes for half the atom in a given sample of an element to decay.  
🗑
radioactive decay   process by which a nucleus spontaneously emits particles or rays to become lighter and more stable.  
🗑
tracer   radioactive element who's pathway can be followed through the steps of a chemical reaction or industrial process.  
🗑
transmutation   process in which one element is chagned into another as a result of changes in a nucleus.  
🗑
nuclear chain reaction   series of fission reactions that occur because the products released during one fission reaction cause fission reactions in other atoms.  
🗑
nuclear fission   splitting of an atomic nucleus into two smaller nuclei of larger mass.  
🗑
transmuranium element   element formed synthetically; has more than 92 protons in its nucleus.  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
