Half-life it tells you about the amount of time needed that half of the quantity of an isotope to disintegrate.
For carbon-14, assuming that the daughter isotope is a stable one and does not disintegrate further, you have:
<u>parent isotope</u> <u>daughter isotope</u> <u>years</u>
100% 0% 0
50% 50% 5,730
25% 75% 11,460
Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat. hope this helps
Nuetrons=neutral
protons =positive
electrons=negative
