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. Though at very high pressure millions of times that of earth it is theorized that is will form into a metal. Gold. SURVEY . Although hydrogen is written above the alkali metals on the periodic table, it is not an alkali metal. It is not a metal It is in Period 1 which contains only two Elements O It has only one electron O It is not highly explosive/reactive Please can anyone do it fast so I can understand lana6795 is waiting for your help. Answer Save. I know it is a gas at room temperature, but that shouldn't matter, I mean, mercury is a liquid at room temperature. 1. 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. Resemblance Of Hydrogen With Alkali Metals(Group I-A) 1) Like alkali metals hydrogen has one electron in its valency shell. Favourite answer. The system of protons and electrons would behave as a fluid. 8 years ago. While hydrogen sits in Group I, it is NOT an alkali metal. Also, as it turns out, if you cool hydrogen to where it solidifies, it can form a metallic structure. answer choices . Hydrogen is a very special element of the periodic table and doesn't belong to any family. Plus, I mean, it IS a metal when you cool it down enough. 2). Log in. ns1 electron configuration as the alkali metals. Removal of its single electron requires considerably more energy than removal of the outer electron for the alkali metals. It is not defined by what it is, but by what it is not. Hydrogen doesn't share many properties with the other Alkali Metals. 8 Answers. 2. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior.
