nuclear chemistry

Alpha particles

1.) low penetrating power

2.) + 2 charge

3.) no electrons

beta particles

1.) 1/1837 amu

2.) -1 charge

3.) medium penetrating power

Gamma rays

1.) electro magnestic radiation

2.) no mass

3.) no charge

4.) high penetrating power


– unstable nucleus

– nucleus will at some point decay to become stable

– energy coming out of nucleus

half- life
The amount of time needed for hlf of a radioactive sample to decay
Natural transmutation
takes place in a naturally occuring unstable isotope when the nucleus emits particles
