Because aluminum replaces compounds of zinc, iron, and copper to produce pure zinc, iron, and copper. Log in. The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: Metals in the middle of the reactivity series, such as iron, will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt, such as iron(II) sulfate: There is some ambiguity at the borderlines between the groups. Iron will react with calcium oxide as iron is more reactive than calcium, therefore calcium (which is the more reactive metal) will displace calcium (the less reactive metal) to form a compound. Rubidium is the "most reactive" among all of them. require more energy (and different methods) to be isolated from their compounds; This page was last edited on 24 November 2020, at 14:33. Yahoo ist Teil von Verizon Media. 1 Answer. Copper and silver will react with nitric acid; but because nitric acid is an oxidizing acid, the oxidizing agent is not the H+ ion as in normal acids, but the NO3− ion. Sie können Ihre Einstellungen jederzeit ändern. 4) Silicon metal will be less reactive than magnesium and aluminum … Barium oxide is more normally made by heating barium carbonate. The electron affinitiy of chlorine will be similar in magnitude to that of iodine, but chlorine's is higher. [1], Comparison with standard electrode potentials, http://www.cod.edu/people/faculty/jarman/richenda/1551_hons_materials/Activity%20series.htm, https://en.wikipedia.org/w/index.php?title=Reactivity_series&oldid=990443795, Articles with failed verification from September 2016, Creative Commons Attribution-ShareAlike License, reacts very slowly with cold water, but rapidly. 5 Answers. Rubidium. Option D. Explanation:. Get your answers by asking now. so francium would be more reactive than cesium. It follows that elements below potassium in the table should be more reactive than potassium is. Magnesium, aluminium and zinc can react with water, but the reaction is usually very slow unless the metal samples are specially prepared to remove the surface layer of oxide which protects the rest of the metal. another area where it's reactive is the last coloumn on the top left. ; In the periodic table, the elements in the lower column have greater outer shell and number of electrons than the upper elements or that in the left side of the row. potassium (k) cesium (cs) magnesium (mg) titanium (ti) - edu-answer.com 1. Join now. aus oder wählen Sie 'Einstellungen verwalten', um weitere Informationen zu erhalten und eine Auswahl zu treffen. Even with this proviso, the electrode potentials of lithium and sodium – and hence their positions in the electrochemical series – appear anomalous. Relevance? Once ignited, barium metal burns in air to give a mixture of white barium oxide, BaO, and barium nitride, Ba3N2. Going from the bottom to the top of the table the metals: There is no unique and fully consistent way to define the reactivity series, but it is common to use the three[failed verification] types of reaction listed below, many of which can be performed in a high-school laboratory (at least as demonstrations).[5]. Find an answer to your question Which element is more reactive than rubidium (Rb)? Rubidium is placed lower in the column and to the right most in the row from the following mentioned elements in the option. Look how pure aluminum rips the chlorine away from the zinc chloride to produce aluminum chloride and zinc. 1 decade ago. Relevance. prahalyaa prahalyaa 13.02.2020 Chemistry Secondary School In chemistry, a reactivity series (or activity series) is an empirical, calculated, and … Favorite Answer. The explanation for this is that rubidium has its single electron farther from the nucleus, where it is more easily removed.
