This happens at any time when addition of the fleeting "weak nuclear force" to the ever-present electrostatic repulsion exceeds the binding energy required to hold the nucleus together.Very careful measurements in laboratories, made on VERY LARGE numbers of U-235 atoms, have shown that each of the atoms has a chance of decaying during about 704,000,000 years.If the nucleus has not yet decayed, there is always that same, slight chance that it will change in the near future.

Explore this link for additional information on the topics covered in this lesson: This activity will help students to have a better understanding of the basic principles used to determine the age of rocks and fossils. Objectives of this activity are: 1) To have students determine relative age of a geologically complex area.

2) To familiarize students with the concept of half-life in radioactive decay.

3) To have students see that individual runs of statistical processes are less predictable than the average of many runs (or that runs with relatively small numbers involved are less dependable than runs with many numbers).

In general, with the exception of the single proton that constitutes the nucleus of the most abundant isotope of hydrogen, the number of neutrons must at least equal the number of protons in an atomic nucleus, because electrostatic repulsion prohibits denser packing of protons.

But if there are too many neutrons, the nucleus is potentially unstable and decay may be triggered.

  1. Bridget’s scene is about a date that she is on and how the boy is just delicious. with just his cock head in her butt hole, he started pumping his cum.. Cum squeezed out as her anus puckered and tightened back to it’s normal shape. Bridget had completely gotten into her acting role as the teenage daughter of Paul.
