an oxide is formed with the general formula MO. Na Thanks Comments; Report Log in to add a comment Looking for something else? All of the group one elements (sodium & potassium etc) and most of the group two elements (calcium etc) will react vigorously and spontaneously in hot water. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. It is likely to be a metal which has a A. high melting point and reacts slowly with water. 1. In each case, a solution of the metal hydroxide is produced together with hydrogen gas. However, given that all the other Group 1 elements react to form colourless solutions of the hydroxide and hydrogen gas (H2), it would be strange if francium not do the same. All the alkali metals react vigorously with cold water. In each case, the aqueous metal hydroxide and hydrogen gas are produced, as shown: (1) 2 X (s) + 2 H 2 O (l) → 2 X O H (a q) + H 2 (g) where X is any Group 1 metal. It uses these reactions to explore the trend in reactivity in Group 1. C. low melting point and reacts vigorously with water. This page looks at the reactions of the Group 1 elements - lithium, sodium, potassium, rubidium and caesium - with water. All of Group 1 elements —lithium, sodium, potassium, rubidium and cesium react vigorously or even explosively with cold water. Quiz 21: Chemistry of the Main-Group Metals; Which Element Reacts Most Vigorously with Water? Which group 1 element reacts the most vigorously? General. Which reacts the most vigorously?

Which element reacts most vigorously with water? K. Li. What happens when the elements in group 1 react with water? Francium is very scarce and expensive. Multiple Choice . You may need to download version 2.0 now from the Chrome Web Store. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. They are soft metals that tarnish quickly in air. This reactivity increases as we move down in a group. Group 1: The Alkali Metals. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Alkali metals react vigorously with water to form hydroxides and dihydrogen. The Facts. Question 33. Activity vs reactivity …. Francium is element number 87 on the periodic table. All the alkali metals react vigorously with halogens to produce salts, the most industrially important of which are NaCl and KCl. Lithium's density is only about half that of water so it floats on the surface, gently fizzing and giving off hydrogen. no reaction. You may need to download version 2.0 now from the Chrome Web Store. (Potassium actually is the more reactive of the two) The reason is that potassium and sodium both lie in Group 1 of the periodic table, which contains all the alkali metals. Looking for something else? Find more answers. an oxide is formed with the general formula M2O. It gradually reacts and disappears, forming a colourless solution of lithium hydroxide. Another way to prevent getting this page in the future is to use Privacy Pass. D. low melting point and reacts slowly with water. Which group 1 element reacts the most vigorously? As far as the elements are placed in periodic table, the more violently they reacts to each other. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Answer. • • Your IP: 138.68.13.164 All of these metals react vigorously or even explosively with cold water. Rubidium is an element in the same group of the periodic table as lithium and sodium. Rate! Related questions. no reaction. Group 1 elements are called the alkali metals. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Also the reactivity in metals increases on moving down the group while that of non-metals decreases on moving down the group. What happens when the elements in group 1 react with oxygen? • Potassium belongs to group 1 and chlorine belongs to group 2. The melting points are all low for metals, as are the densities of these elements. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. Performance & security by Cloudflare, Please complete the security check to access. 2. A)Al B)Li C)Ba D)Mg E)Cs. a. Li b. Na c. K d. Rb e. Cs. The Group 1 metals get more reactive as we go down the group. Hence chlorine and potassium will react more violently.
