Hydrogen is widely used in power stations as a coolant in generators. Periodic table makers sometimes get away with duplicating hydrogen above the alkali metals and the halogens, ... Hydrogen is thus in the unique position of being just as likely to want to gain an electron as to lose the one it has; either way, it reaches a stable valence state. Hence the differences between authors of texts and where they put Hydrogen on their periodic table. Hydrogen is the 1st element in the modern periodic table. Introduction and Discovery of Hydrogen - Duration: 3:10. The electronic structure is written as 1s 1. Forget 10 Downing Street or 1600 Pennsylvania Avenue, the most prestigious address in the universe is number one in the periodic table, hydrogen. It has electronic configuration ls1. “Hydrogen is formally a member of group 1, but its chemis-try is usually dealt with separately from the other elements” (9). This difference in mass number arises because the nucleus contains a different number of neutrons. Thus, hydrogen was put at the top of the periodic table so that the symmetry of the modern periodic table is not disturbed. Position of Hydrogen. науки,МАНУ, 38 (1), 83–90 (2017) 87 Figure 5.The Labarca & Srivaths PT [34]. Hydrogen is the smallest and the lightest element and has the first position which is an unique position in the periodic table. Properties of Hydrogen are similar to properties of Halgens as electronic configurations of halogens and Hydrogen are same. In its properties, it behaves like alkali metals as well as halogens. Hydrogen occupies a unique position in modern periodic table, justify the statement. In fact, the chemistry of hydrogen does not greatly resemble that of the metals of Group 1. Show abstract. View. Recent arguments in favor of placing hydrogen either separately at the top of the table or as a member of the carbon family are shown to have serious defects. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Thomsen 1 and Bohr 2 depicted hydrogen in a central position with a lineage relationship to both the alkali (Group I) and the halogen (Group VII) elements. Most versions of the periodic table place hydrogen in the upper left corner immediately above lithium, implying that hydrogen, with a 1s 1 electron configuration, is a member of group 1. This unique type of bonding may vary in strength . one main point of contention in the previous attempts was the position of hydrogen in the periodic table. Hydrogen is the first element of the periodic table having atomic number 1. 4)It exist as a diatomic molecule i.e. continuo usly: on one end, ... About the position of hydrogen in the periodic table and the nature of elements. neither with alkali metals nor with halogens. The position of hydrogen in the periodic system is a debatable topic. Other authors of chemistry textbooks realize that hydrogen seems to love the gas-phase so much over the solid phase that it just doesn't make sense to call it a metal, irrespective of what atomic orbital pattern may tell us.
