A radioactive isotope decays at a constant rate proportional to the number of radioactive atoms remaining. A simple way of describing the speed of decay is to see the time it takes for half of the atoms of a radioactive parent to decay and form the daughter element(s). This is called the half life.
Hope this helps

The sensory cells present on our retina that are responsible for our vision are known as rod cells and cone cells. Rod cells do not allow us to see in color, only black and white, and are better in low-light conditions. Cone cells are responsible for our ability to see colors but are bad in low-light conditions. Cone cells are able to sense red, green and blue colors. When one type of the cells will be stimulated, the remaining will show an "afterimage" due to the overstimulation of the complementary cells.
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.
