Problem 4: Predict the most likely modes of decay and the products of decay of the following nuclides: a 17F b 105Ag c 185Ta We should be able to predict the mass of an atom from the masses of the subatomic particles it contains.
It has a positive charge of the same size as the negative charge on the electron, and the same mass as an electron.
This decay occurs at a constant, predictable rate that is referred to as half-life.
Yellow and orange are progressively less stable, with half-lives in thousands or hundreds of years, down toward one day.
As the decay process produces an , some of the proposed explanations for the observed rate oscillation invoke neutrino properties.
consist of two protons and two bound together into a particle identical to a helium nucleus.
