justify the position of hydrogen in the modern periodic table

Metals are found on the left side and centre of the Modern Periodic Table. That is why position of hydrogen is still undecided. H + Modern periodic Law: The properties of elements are a periodic function of their atomic number. Lithium 1s 2 2s 1. Watch Video Solution On Doubtnut App Exercise 9.3. Ask questions, doubts, problems and we will help you. In the modern periodic table, elements are in order of atomic number in periods and groups. Horizontal rows of the periodic table of elements are the periods. Hydrogen Ncert Video Solutions - Only On Doubtnut Download Doubtnut Now Exercise 9.1 Justify the position of hydrogen in the periodic table on the basis of its electronic configuration. The position of some elements which were misfit on the basis of atomic mass is now justified on the basis of atomic number. Accepted Answer: Though hydrogen is a non-metal, it has been placed at the top of group 1 above the alkali metals because its electronic configuration is similar to alkali metals i.e. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Mendeleev made an early periodic table. Its electronic configuration is [1s 1 ]. Download Citation | Concerning the position of hydrogen in the periodic table | The placement of hydrogen in the periodic table has unique implications for fundamental questions of chemical behavior. Electronic configurations model how electrons are arranged in atoms. Justify the statement. why is position assigned to hydrogen in the modern periodic table considered anomalous - - TopperLearning.com | 99i8x2fmm All noble gases are at the extreme right of the table (in most table). Hydrogen and alkali metals have similar outer electronic configuration as both have one electron in their outermost shell. Properties of Hydrogen are similar to properties of Halogens as electronic configurations of halogens and Hydrogen are same. The prime factor is the proton number. #class10#periodicclassificationofelements“Hydrogen occupies a unique position in Modern Periodic Table”.Justify the statement. Due to the presence of only one electron in its 1s shell, hydrogen exhibits a dual behaviour, i.e., it resembles both alkali metals and halogens. 2) Electropositive character: Like alkali metals ,hydrogen also loses its only electron to form hydrogen ion i.e. 2. Non-metals are found on the right side of the Modern Periodic Table. It’s a noble gas. Justify the position of Hydrogen in the periodic table? Sometimes hydrogen loses electron like Group I elements and sometimes it gains electrons like those of group VII. (Those frivolous Europeans do not have such limitations, and you can freely buy tritium key chains, tritium fishing lures, probably tritium bellybutton rings if you look hard enough.) Class 11 Chemistry - Hydrogen | Position of Hydrogen In the Periodic Table - Duration: 6:37. Hydrogen’s position was not justified in the very old Mendeleev’s periodic table. He did so because hydrogen and alkali metals have similar properties. Hydrogen occupies a unique position in modern periodic table, justify the statement. Look, in the modern periodic table of elements, there are many factors on which elwments are arranged. He positioned hydrogen in the first column above alkali metals. Key words: hydrogen; position of; Periodic Table; trends; hydrogen bonding PROLOGUE In addition to the numerous works in mo-lecular spectroscopy (mostly hydrogen-bonded sys- tems, particularly crystalline hydrates) it has to be recognized that our laureate was the first one that introduced modern courses of chemistry education for chemistry majors (in the early 1990‟s)at the Ss. Thanks for the A2A. The position of hydrogen was not justified in Mendeleev’s periodic table. Therefore, the present position of hydrogen in the modern periodic table is not completely justified. The Questions and Answers of Hydrogen occupies a unique position in Modern Periodic Table”. are solved by group of students and teacher of Class 10, which is also the largest student community of Class 10. (have 1 valence electron in the outermost shell) Li , K , Na , K, Rb ,Cs and Fr of group 1 of the periodic table. 32. See that purple ‘He’ at the top right corner? For example, hydrogen reacts with halogens, oxygen, and sulphur to form compounds whose formulae are similar to those of alkali metals. Skip to main content ; Periodic Table. Hydrogen is the first element of the periodic table. Hydrogen has been placed at the top of the alkali metal family. Hydrogen resembles the elements of group I-A, IV-A and VII-A in some respects. So the answer is False . Hydrogen is the first element in the periodic table. 6:37. Hydrogen loses 1 electron and behaves like electropositive alkali metals [Group 1 (IA)]. The placement of hydrogen in the periodic table has unique implications for fundamental questions of chemical behavior. Although Mendeleev arranged the elements in the increasing order of their atomic masses, there were instances where he had placed an element with a slightly higher atomic mass before an element with a slightly lower atomic mass. Due to this property of hydrogen, it can be placed either in group I or group VII. Hydrogen gains 1 electron and behaves like electronegative halogens [Group 17 (VIIA)]. Hydrogen occupies a unique position in the modern periodic table due to the following reasons
(i) Both hydrogen and alkali metals metals have similar outer electronic configuration as both have one electron in the valence shell. 1. 2 See answers SHIVAMBANDE18122005 SHIVAMBANDE18122005 Explanation: Hydrogen is the first element of the periodic table & often called protium. Sodium 1s 2 2s 2 2p 6 3s 1. Ramirez-Torres4 has presented a block form table with hydrogen placed in an isolated group unrelated to either the alkali or halogen elements. Its atomic number is 1, and it has only one electron in its valence shell. Hydrogen and alkali metals resemble in the following aspects. For example, argon precedes potassium because argon has atomic number 18 and potassium has 19. Hydrogen (Z=1) has electronic configuration 1s1. The lanthanoids and actinoids which have properties different from other groups are placed separately at the bottom of the periodic table. Hydrogen 1s 1. 10 Periodic Table in 8K resolution 11 Other properties of Magnesium Magnesium is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure. Definition, mass & chemical names. So, it belongs to the first group and the first period of the periodic table. Hydrogen resembles alkali metals i.e. It’s atomic number is 2. Hydrogen has the electronic configuration 1. My Periodic Table is such a registered location now, and the marker you see here is screwed down with three spanner-head tamper-proof screws per manufacturers recommendation. Metalloids are found in a zig-zag manner between the metals and the non-metals. Hydrogen Hydrogen is one of the three most abundant elements present on Earth. MBD Alchemie 2,708 views. 1) Electronic configuration : Like alkali metals, hydrogen also contains 1 electron in its outermost shell.
