History. Some do. The noble gases all have 8 which is the maximum capacity, so they cannot easily share electrons with other elements. Answer Save. Although it is known that krypton and radon also form compounds, the compounds of krypton and radon are rarely studied as both their instability and their radioactivity make their handling problematic. They traditionally have been labeled Group 0 in the periodic table because for decades after their discovery it was believed that they could not bond to other atoms ; that is, that their atoms could not combine with those of other elements to form chemical compounds . Helium, neon, and argon do not combine with any other elements to form compounds. The atoms of all six gases have outer energy levels containing eight electrons. The heavier noble gases, in contrast, do form a limited number of compounds. But noble gasses already have 8 so they don't form compounds:D. 0 0. gmanwill. C. What is the name of a binary compound made of lithium and chlorine? The heavier noble gases have more electron shells than the lighter ones. A. Several Noble gases form compounds, with some mixture of ionic and covalent character to the bonds involved. Other characteristics of the noble gasses are that they all conduct electricity, fluoresce, are odourless and colourless, and are used under several conditions where a stable element is needed to maintain a healthy and constant environment. noble gas form compounds with oxygen and fluorine only because they are most electronegative elements. Log in. Under any practical circumstances or even STP, these gases never form compounds and therefore it is safe to assume that these Noble Gases very rarely form bonds with other atoms. why do noble gas form compounds with oxygen and flourine only? Thus, xenon forms divalent to octavalent compounds. Best answer. The reason that these organizations of valance electrons don't form many compounds is because each individual atom's electron structure is extremely stable, and thus for them to react with another atom (or atoms), the stability of the resulting compound would need to … There are theoretical cases of neon fluoride compounds and a proven HArF compound that can be created at controlled conditions. Xenon forms compounds because its inner electrons screen the outer electrons from the nucleus. The noble gases group were once thought to be part of group zero, due to the fact that they do not form compounds with other elements, because of their atoms. Fluorides can also be used as fluorinating reagents. Why do the noble gases not form compounds readily? Anonymous. 2 See answers Answer 5.0 /5 3. 1. Why do the noble gases NOT form compounds readily? In recent years, however, this term has fallen out of favor, although you will occasionally see it in older literature. They form compounds like XeF2, XeF4, XeO2, with a mixture of covalent and ionic characters; the electrons are being shared by the F atom and the Xe atom, although the Xe does not obey the so called Octet Rule. Log in. The thing to remember is that they were forced. Because of their high ionization energy and almost zero electron affinity, they were not expected to be reactive. why are the noble gases inert? Why do some of the noble gases form compounds? 1. The noble gases were originally also referred to as “inert gases,” since it was believed that they did not react with other elements to form compounds. 1 0. Share 11. Noble gases have eight electrons in their outer shell. 2 Answers. > Its outer electrons then become a target for other highly electronegative atoms. They have completely filled electron shells with no have-filled orbitals available for making covalent bonds and they have very high ionization energies so they don't form ions. Join Yahoo … Discovery of noble gas Compounds. because of the fact they're noble gases, and as a definition of that, the octet rule is happy for the component. Owing to their low reactivity, only a few chemical compounds of these gases have been formed as of today. in an ionic bond the non metals is always negative aka. We are too complete in our electron shells to mate with other, less noble elements. Get the answers you need, now! Although the noble gases are generally nonreactive elements, many such compounds have been observed, particularly involving the element xenon. They have empty outer energy levels B. 1 Answer +1 vote . Lv 7. [1] William Ramsay discovered most of noble … of some noble gases. Noble Gas Chemistry The noble gases are the least reactive of all the elements but the heavier ones do form some molecules. in an ionic bond the metals is always posotive aka. But Wait, They Do Bond! So they can ionise noble gases also. Why do some noble gases form compounds with fluorine and oxygen only ? Ask your question. 0 0. Because of … They have no tendency to lose, gain, or share electrons. Queries asked on Sunday & after 7pm from Monday to Saturday will be answered after 12pm the next working day. according to bohrs model, how do electrons behave? Because their octet of valence electrons is already complete. In this column are some very unique elements called the noble gases. answered Dec 19, 2017 by Md samim (94.8k points) edited Jul 15, 2018 by sanjeev . they do not gain or loose electrons to form ions. However highly reactive elements can sometimes even react with noble gases, like fluorine. The low reactivity of the noble gases can be explained by their electronic structure. 1. share | improve this question | follow | edited Oct 21 '15 at 6:24. A new idea explains recently discovered chemistry that seems to break the rules of high school textbooks everywhere However, they soon discovered that the noble gases do indeed form some compounds with some other elements and have eight valence electrons. In 1962 English chemist Neil Bartlett (1932–) succeeded in preparing the first compound of a noble gas, a compound of xenon. Explaining the inertness of noble gases. 2. noble gases could not form compounds due to their full valence shell o… The noble gases are colourless, odourless, tasteless, nonflammable gases. 2 years ago. nonmetals and metals . Roger the Mole. These are helium, neon, argon, krypton, xenon, and radon. Still have questions? negative. Noble gas is translated from the German noun Edelgas, first used in 1898 by Hugo Erdmann to indicate their extremely low level of reactivity. However, its high radioactivity and short half-life are the key factors which prevent this. They were also believed to have a valence of zero. Some have been used in compounds to make explosives, and others just form compounds in a lab. and do not take part in chemical reactions. Ask Doubt. According to the octet rule noble gases should not form compounds but xenon and krypton form compounds like $\ce{XeF2}$, $\ce{XeF4}$, $\ce{XeOF2}$ and $\ce{KrF2}$ respectively. Only some noble gases tend to form compounds, such as xenon and krypton.However, some like helium, almost have no compounds at all. Answered by | 3rd Aug, 2008, 03:45: PM. They have no electrons C. They have seven electrons in the outer energy levels D. Their outer energy levels are completely filled with electrons. inorganic-chemistry theoretical-chemistry noble-gases. Although noble gasses usually do not react to form compounds with other elements, there are some exceptions. Therefore, they do not form compounds. Explain why some noble gases such as Xe will form compounds and some such as Ne will not? caution. Not all the noble gases combine with oxygen and fluorine. Since Noble gases already have a full outer shell, they do not need to do this. This is why the noble gases are inert and do not take part in chemical reactions. For a long time, many people believed the noble gases to be completely nonreactive and unable to form chemical compounds. p - block element; Share It On Facebook Twitter Email. It was only when scientists discovered that some of these gases do have the ability to form compounds – on a much smaller scale though, that the use of term ‘Zero Group’ was discontinued. D, they are completely filled with electrons (helium has 2 outer electrons and the other noble gasses have 8, which are all full) 0 0. The compound was xenon platinofluoride (XePtF 6 ). Helium and neon never form molecules. In order to make a compound, an element has to lose, gain or share electrons. At high pressure, even helium, neon, and argon participate in chemical reactions. Anonymous. Hope this helped :)- As noble gases show extremely low chemical reactivity, while they are not inert, only a few hundred noble gas compounds have been formed to date, with xenon varieties making up the bulk. Rate! They both do not have a measured electronegativity. Because some noble gas compounds have powerful oxidizing properties, they have been used to synthesize other compounds. A. Chlorine lithiate B. chlorine lithium C. Lithium Chloride D. Lithium chlorate. Noble gas compounds are chemical compounds that include an element from the noble gases. However for almost all practical purposes are stable. what is the charge on an atom? Noble gases also have octet rule shells, which causes the little reactivity associated with them.. To form bonds with noble gases, a lot of energy is required to form those bonds. 2 years ago. What are the properties of the noble gases? 0. ionic bonds form. Asked by | 2nd Aug, 2008, 11:32: PM. As of about 40 years ago, scientists have been able to make some compounds with noble gases. Share with your friends. Get answers by asking now. 5.0 1 vote 1 vote Rate! Although these elements don't form compounds readily, examples of molecules containing xenon, krypton, and radon have been found.
