Plus, I mean, it IS a metal when you cool it down enough. Hydrogen, with a solitary electron, is usually placed at the top of Group 1 of the periodic table, but it is not considered an alkali metal; rather it exists naturally as a diatomic gas. Although hydrogen has ns1 electron configuration just like alkali metals, it is still not a metal because it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than other alkali metals. Why is Hydrogen not included in the Alkali metal Family? 1 See answer raaziyaa is waiting for your help. Whilst hydrogen do not exactly fit in group 1 as an "alkali metal" (it's a gas instead of a metal, except in special conditions, it forms negatively-charged ions, and it is far less electropositive than lithium), it absolutely cannot be a halogen.

Alkali metal, any of the six elements of Group 1 (Ia) of the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium. 20 seconds . Though at very high pressure millions of times that of earth it is theorized that is will form into a metal. Like alkali metals,H forms positive hydrogen. maybe. The May 6, 1998 edition of Cornell News states, “Last year liquid metallic hydrogen was created for less than a microsecond by scientists at Lawrence Livermore National Laboratory in California.” Hydrogen Metal Liquid. Ask your question. It is the lightest and simplest having only one proton and one electron. 2). Hydrogen is a non-metal, it is one of the two elements on the periodic table that only need two valence electrons to be stable. Hydrogen is not a metal because it does not have following properties that all the metals exhibit:-----metal, chemical ELEMENT displaying certain properties, notably metallic luster, the capacity to lose electrons and form a positive ION, and the ability to conduct heat and electricity (see CONDUCTION), by which it is normally distinguished from a nonmetal. SURVEY . Click here to get an answer to your question ️ why did hydrogen called an alkali metal 1. Hydrogen is in the alkali metal family (or lithium family), but is not classified as an alkali metal. The alkali metals dissolve slowly in liquid ammonia, forming ammoniacal solutions of solvated metal cation M + and solvated electron e −, which react to form hydrogen gas and the alkali metal amide (MNH 2, where M represents an alkali metal): this was first noted by Humphry Davy in … no. A Hydrogen atom is an element. Reactivity of Group 1 Elements. Favourite answer. Find an answer to your question Why is hydrogen placed in the first group if it is not an alkali metal? Hydrogen is a considered a nonmetal at normal temperature and pressure. For the first time, scientists have shown that hydrogen can stand in for alkali metals in typical alkali metal structures. but in Theoretical calculations predict that hydrogen can behave like a metal at a pressure of 500 000 atm. Hydrogen doesn't share many properties with the other Alkali Metals. 8 years ago. Join now. You can oxidize it into H2O, same with Lithium, you can get Li2O and potassium you can have K2O. Hydrogen is a Non-Metal. The first element in the periodic table is hydrogen.Here are some reasons for the position of hydrogen: It resembles alkali metals and halogens. Although hydrogen is written above the alkali metals on the periodic table, it is not an alkali metal. Log in. The reason that Hydrogen is not included as a Alkali Metal or in the Halogen Family (or any group, for that matter) is because it can act as a metal or nonmetal. ns1 electron configuration as the alkali metals. 2. Log in. Firstly, most of the ambiguities associated with hydrogen as a metal or a non metal, comes from its ability to exhibits the properties of both groups. Hydrogen forms positive ions and reacts in very similar ways to the alkali metals. 8 Answers. Hydrogen isn't classified as an alkali metal because it exhibits several properties that are not found in the alkali metal group, including the tendency to be found as a diatomic molecule, a tendency to form weak bonds with other bound hydrogen atoms nearby, weak electromagnetism, a low activity series placement, and the tendency to be found as a gas. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior. Hydrogen ion (specifically the one with a +1 charge) is usually found in acids (Acids can be defined as a compound that produces H+ ions when dissolved in water). Log in. Which gas is released when the alkali metals react with water? Assuming all … Hydrogen is a very reactive gas, and the alkali metals are even more reactive. andreeaalexa andreeaalexa Generally, metals GIVE AWAY their outer shell electrons, hydrogen usually GAINS an electron in order to become stable. The next alkaline earth metal after radium is thought to be element 120, although this may not be true due to relativistic effects. SURVEY . Which is not a Alkali Metal? TejuKamath 13.05.2016 Chemistry Secondary School +5 pts. Solid hydrogen, an electrical insulator, is predicted to become an alkali metal under extreme compression, although controversy surrounds the pressure required to achieve this1,2,3. Explanation H (Z=1): K1. Consequently, a new metal surface in contact with water is formed, which explains why the reaction does not become self-quenched by its products, but can rather lead to explosive behaviour. Tags: Question 29 . 3. Potassium. Hydrogen though is non-metal lies in "Alkali metal" group(1).Why? Liquid hydrogen metal would have no rigid matrix. Ask your question. An alkali on the other hand are bases and they form OH- ions when dissolved in water. Answer Save. 1. It is not defined by what it is, but by what it is not. Median response time is 34 minutes and may be longer for new subjects. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
