It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
The principle behind the use of radioactive tracers is that an atom in a chemical compound is replaced by another atom, of the same chemical element. The substituting atom, however, is a radioactive isotope. This process is often called radioactive labeling.

Yes, for over thousands of years snow, ice and glaciers have been slowly moving. In the process they make a deep valley or gorge from all the erosion.
Not according to the strict chemistry definition. You can, however, fission an element into smaller pieces.
Living organisms slowly modify the evironment
A property of that element. An unstable element. A radioactive element
Daughter Elements

When bones, or other dense living material is buried, over thousands of years as it decays it leaves spaces where minerals can gather. As the bone/ivory/shell/whatever, decays it is slowly replaced with mineral deposits that when the substance is fully decayed will fill in the hole that would have been left, and that mineral form is the fossil.
An obvious one is the movement of the tectonic plates.
An apple decays over the period of around 1-2 months depending on the conditions that it is in. To help with the decomposition process, humidity in the air can attract insects to decay the apple.
An atom whose nucleus decays over time is called radioactive. Some examples of radioactive substances are uranium, plutonium, and einsteinium.
A cliff can change over time by the process of erosion. This process erodes parts of the cliff away slowly and then, when erosion stops taking place to the cliff, the cliff stops changing.
As they adapt to their environment, they slowly change over time. They are said to Evolve.
You play the notes slowly and speed up over time. With that process, you will be able to master that song.
There are numerous things on Earth that change very slowly. Some examples include land forms, mountains, reputations, and civil rights.
The heme in the red blood cells decays over time into other compounds, one of which appears slightly greenish. The green compound then decays further into a yellowish compound.
