Start with the Half-Life tab. Press the pause button. Then, press Add 10 one time to add 10 atoms of carbon-14. Next. press the play button and watch the timeline at the top of the screen.
Press Reset All Nuclei, and watch the timeline again. Repeat this process several times.
When do the C-14 atoms decay on each repetition?
O always after the half-life mark
O always before the half-life mark
O at random times
O at the same time
O in 1,000-year intervals
