There are four types of crystalline solids. The four types of crystalline solids includes the ionic solid, molecular solids, atomic solids and the metallic solids.
An alpha particle, 42He
Polonium-218-------------alpha---------------Lead-214
No, it's a long chain. The decay sequence is: Uranium-238 to thorium-234 to protactinium-234 to Uranium-234 to thorium-230 to radium-226 to radon-222 to polonium-218 to lead-214 to bismuth-214 to polonium-214 to lead-210 to bismuth-210 to polonium-210 to lead-206 which is its final stable form. Radioactive decay occurs when an unstable (radioactive) isotope transforms to a more stable isotope, generally by emitting a subatomic particle such as an alpha or beta particle (helium nucleus or electron). The half-life of one of the elements above can be shorter than a millisecond (Po-214) or as long as 4.5 billion years (U-238).
