AdiChemistry Home The le Chatelier's principle can be stated as: When external stress is applied on a system at dynamic equilibrium, the system shifts the position of equilibrium so as to nullify the effect of stress. Stress can be applied on chemical systems by changing the concentration or pressure or temperature.

Fission isa reaction when the nucleus of an atom, having captured a neutron, splits into two or more nuclei, and in so doing, releases a significant amount of energy as well as more neutrons. These neutrons then go on to split more nuclei and a chain reaction takes place.

Writing Alpha and Beta Decay Equations Return to Radioactivity Menu Go to positron decay and electron capture First off, you need to know how to write and understand nuclear symbols: Remember that the lower number is the atomic number and the upper number is the mass number.

Great site for nuclear chemistry if you are a visual learner.

This is a small review for the ACS final. There are also similar videos attached.

This is a 3 part video that breaks down the elements of nuclear chemistry

This site gives a great overview of nuclear chemistry, along with radioactive decay.
