|---|---|---|---|---|---|
| Radioactivity | The process by which an unstable nucleus emits one or more particles of energy in the form of electromagnetic radiation
🗑
|
||||
| Nuclear Radiation | The particles that are released from the nucleus during radioactive decay
🗑
|

| Four types of nuclear radiation | Alpha particles, Gamma Particles, Beta Particles, Neutron emissions
🗑
|
||||
| Alpha particles | Positively charged atom that is released in the disintegration of radioactive elements
🗑
|
||||
| Gamma particles | The high-energy photon emitted by a nucleus during fission and radioactive decay
🗑
|
||||
| Beta particles | A charged electron emitted during certain types of radioactive decay
🗑
|
||||
| Neutron emissions | Consists of matter that is emitted from an unstable nucleus
🗑

| Nuclear Decay | ohhhh baby!
🗑
|
||||
| Half-life | The time required for half of a sample of a radioactive substance to disintegrate by radioactive decay or by natural processes
🗑

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.
