Dmitri Ivanovich Mendeleev (1834-1907), the Russian chemist who first proposed in 1869 the principle known as the periodic law of chemical elements, stated that the physical and chemical properties of the chemical elements are a periodic function of their proton number also known as atomic number. For a neutral atom, this number is equal to the number of electrons orbiting the nucleus. Since Mendeleev’s periodic classification of all basic building blocks of matter, more than 112 chemical elements have been discovered or synthesized. However, element with atomic number 112 is called Copernicium in honor of Nicolaus Copernicus (1473-1543), Polish astronomer, who in 1514 revived the idea of a heliocentric universe. This idealized mathematical model was first proposed by Aristarchus of Samos in 310-230 BCE but was dropped in favor of the geocentric universe proposed by Ptolemy (90-168 CE). Although there is no theoretical limit to the number of planets or protons, the common denominator between real planets and protons is the existence of attractive forces. The first is the attractive gravitational force. The second is the attractive strong nuclear force. However, both forces are known to depend on the critical distances between their respective particles of matter such that for the Solar System there can but limited to 8 planets, while for the nucleus there can but limited to certain numbers of protons.
