The periodic table allows chemists a shortcut by arranging typical elements according to their properties and putting the others into groups or families with similar chemical characteristics. Historically, however, relative atomic masses were used by scientists trying to organise the elements. * the elements in the periodic table are arranged in the increasing order of the atomic number. The chemistry periodic table appears confusing at first glance, but the information in the element table has a logical explanation and is less complex but who invented the periodic table of the elements? The modern periodic table lists the elements in order of increasing atomic number (the number of protons in the nucleus of an atom). Rows of the modern periodic table are called periods , as they are in mendeleev's table. This was mainly because the idea of atoms being made up. Interactive periodic table showing names, electrons, and oxidation states. Given the number of properties for each element and its many applications, how the table should look has long been a subject of debate. Hydrogen (h) and helium (he). For relative abundances of isotopes in nature see reference on atomic weights and isotopic compositions.
Electronic configurations model how electrons are arranged after the discovery of protons, scientists realised that the atomic number of an element is the same as the number of protons in its nucleus. The atomic number of each element increases than the element preceds it in the same period by whole one , each period begins by filling a new energy level with one electron , then filling the atomic energy sublevels lying in the same period successively , until we reach the last. Variation in the number of electrons or neutrons does not. The atomic number is how many protons an atom of that element contains.
