The Speed of Light and the Number of Chemical Elements.

Abstract

Using the particle-wave dualism of microparticles and the Bohr model of the atom, it is strictly shown that the maximum number of chemical elements in the periodic table cannot be more than 137. Since, starting from element 138, the speed of a 1S-electron when moving around the nucleus of an atom must be higher than the speed light in a vacuum. Therefore, Feynmanium (Z=137) is the last chemical element. It was also shown that a decrease in the half-life of chemical elements correlates with an increase in the 1S-electron relativism.
