PPT-Radioactive Dating Nature’s Clock

When sedimentary rock is deposited in layers it is deposited horizontally Scientists use this Principle of Original Horizontality to help them determine the age of the layers The older layers of rock are found below the younger layers of rock. localisation.

Macroscopic Effects. Types of Decay. The Decay Chain. Fission. Radioactive Decay - Jim Hartnett. 2. Radioactive Decay. A nucleus may be bound in a relatively high energy state, and if it can attain a lower energy, it will eventually do so. Why are some elements (isotopes) more stable than others?. The Nucleus. The Electric Force. Protons hate Protons. Strong Force. Strong Force Facts. Neutrons act like cement. Strong Force is very strong over a small distance (about the distance of two protons). Nuclear Stability . Nuclear stability . means that nucleus is stable meaning . that it . does not spontaneously emit any kind of radioactivity (radiation). . On the other hand, . if the . nucleus is unstable (not stable), it has the tendency of emitting some kind of . And it’s relationship to the Genesis account of creation. (Genesis 5). Christadelphian.

When the nucleus of an atom possesses either too many or too few neutrons compared to the number of protons it becomes unstable. These are called radioactive isotopes.
