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. Ask Question + 100. Under most conditions, aluminum is "more reactive", in the sense that metallic aluminum will replace iron in solution, thus 'precipitating' iron. - 15332312 1. No, rubidium is more reactive than potassium. The order of reactivity, as shown by the vigour of the reaction with water or the speed at which the metal surface tarnishes in air, appears to be, the same as the reverse order of the (gas-phase) ionization energies. Damit Verizon Media und unsere Partner Ihre personenbezogenen Daten verarbeiten können, wählen Sie bitte 'Ich stimme zu.' ★★★ Correct answer to the question: Based on its location on the periodic table, which metal is likely to be less reactive than rubidium and more reactive than calcium? Daten über Ihr Gerät und Ihre Internetverbindung, darunter Ihre IP-Adresse, Such- und Browsingaktivität bei Ihrer Nutzung der Websites und Apps von Verizon Media. Which metal is more reactive: Potassium or Rubidium? so francium would be more reactive than cesium. 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]. Look how pure aluminum rips the chlorine away from the zinc chloride to produce aluminum chloride and zinc. Rubidium. Für nähere Informationen zur Nutzung Ihrer Daten lesen Sie bitte unsere Datenschutzerklärung und Cookie-Richtlinie. 2) Ionization energy of rubidium will be less than that for sodium. A bigger explosion does not always mean more reactive, sodium explodes more violently with water than caesium but caesium is more reactive. Thus, the force of attraction between nucleus and the outermost shell decreases going down the group as it is easier for rubidium to release its outermost shell than sodium and resulting Rubidium is more reactive than sodium. In chemistry, a reactivity series (or activity series) is an empirical, calculated, and … Explain why cesium is more reactive than Rubidium or Barium? 5 Answers. Option D. Explanation:. 1 decade ago. 1 0. The explanation for this is that rubidium has its single electron farther from the nucleus, where it is more easily removed. Favorite Answer. another area where it's reactive is the last coloumn on the top left. 1 Answer. This is borne out by the extraction of metallic lithium by the electrolysis of a eutectic mixture of lithium chloride and potassium chloride: lithium metal is formed at the cathode, not potassium. aus oder wählen Sie 'Einstellungen verwalten', um weitere Informationen zu erhalten und eine Auswahl zu treffen. [2][3][4] It is used to summarize information about the reactions of metals with acids and water, single displacement reactions and the extraction of metals from their ores. RbCl will be the most exothermic. Even with this proviso, the electrode potentials of lithium and sodium – and hence their positions in the electrochemical series – appear anomalous. Dies geschieht in Ihren Datenschutzeinstellungen. Thanks. 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. Join now. require more energy (and different methods) to be isolated from their compounds; This page was last edited on 24 November 2020, at 14:33. Because aluminum replaces compounds of zinc, iron, and copper to produce pure zinc, iron, and copper. The electron affinitiy of chlorine will be similar in magnitude to that of iodine, but chlorine's is higher. Relevance? prahalyaa prahalyaa 13.02.2020 Chemistry Secondary School Still have questions? Answer Save. Answer Save. The reactivity series is sometimes quoted in the strict reverse order of standard electrode potentials, when it is also known as the "electrochemical series": The positions of lithium and sodium are changed on such a series; gold and platinum are in joint position and not gold leading, although this has little practical significance as both metals are highly unreactive. Dazu gehört der Widerspruch gegen die Verarbeitung Ihrer Daten durch Partner für deren berechtigte Interessen. 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. Ask your question. Sie können Ihre Einstellungen jederzeit ändern. A. aluminum (Al) B. cesium (Cs) C. strontium (Sr) D. beryllium (Be) Similarly, atoms of potassium (K in the table) are larger, and so more reactive, than atoms of sodium. Relevance. Explain.?
