Near the end of the nineteenth century, reigned in the view of science, where the smallest, indivisible part of matter further is the atom Near the end of the nineteenth century, reigned in the view of science, where the smallest, indivisible part of matter further is the atom. Only research conducted at the end of the nineteenth and early twentieth century helped to establish that the atom has a complex and in addition the construction of electricity. The construction of the atom to explain the processes occurring during chemical reactions. Atom - no matter what the element - consists of a kernel of atom, which represents almost the entire mass of the atom and the electrons circulating at high speed on the orbits around the kernel. The mass of an atom is the kernel 1840 times the mass of the electron. The core of an atom consists of a turn of the neutrons and protons and have an electric charge, while the electron has a negative load. The normal build atom number of electrons is equal to the number of protons, the result that it is electrically neutral on the outside. Construction of the simplest atom is hydrogen atom. The kernel is the only one proton, around which only a circling electron. Each element has a different construction of the atom. Depending on the type of structure element is more or less complex. Atom of each element has a specified number of electrons and atomic nucleus must have a mass of at an appropriate amount of protons, so that could tie together all the electrons circulating in various orbits around the kernel.
