We now know that the experiments failed for two simple but important reasons:. 1. Atoms send out a burst of light energy about every 10. -8 . s so the probability that the atoms in each source would emit their light waves in phase is nearly zero – the result is an interference pattern that changes in an irregular fashion and is impossible to see. True. False. Every point of a wave front may be considered the source of secondary wavelets that spread out in all directions with a speed equal to the speed of propagation of the wave..

The number of electrons is equal to the number of protons = Atomic Number. Alpha Decay . Alpha decay. occurs for those nuclides which have an atomic number greater than 82. Such heavy nuclides have no stable configuration of neutrons and protons, and as a result, emit an alpha particle consisting of 2 protons and 2 neutrons.. FNAL PAC 20 June 2016. Caveats.
