Rubidium is the "most reactive" among all of them. 1 0. aus oder wählen Sie 'Einstellungen verwalten', um weitere Informationen zu erhalten und eine Auswahl zu treffen. In chemistry, a reactivity series (or activity series) is an empirical, calculated, and … 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. Yahoo ist Teil von Verizon Media. Favorite Answer. 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. ★★★ 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? Rubidium is placed lower in the column and to the right most in the row from the following mentioned elements in the option. potassium (k) cesium (cs) magnesium (mg) titanium (ti) - edu-answer.com another area where it's reactive is the last coloumn on the top left. It is below Potassium in the periodic table. It follows that elements below potassium in the table should be more reactive than potassium is. Ask your question. However, they are only valid for standard conditions: in particular, they only apply to reactions in aqueous solution. require more energy (and different methods) to be isolated from their compounds; This page was last edited on 24 November 2020, at 14:33. Thanks. Standard electrode potentials offer a quantitative measure of the power of a reducing agent, rather than the qualitative considerations of other reactive series. so francium would be more reactive than cesium. A bigger explosion does not always mean more reactive, sodium explodes more violently with water than caesium but caesium is more reactive.

Join Yahoo Answers and get 100 points today. Find an answer to your question Which element is more reactive than rubidium (Rb)? Even with this proviso, the electrode potentials of lithium and sodium – and hence their positions in the electrochemical series – appear anomalous. 1 decade ago. In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression[1] of a series of metals, arranged by their "reactivity" from highest to lowest. if you look in the periodic table of elements cesium is in the period 1 group and the lower the element in that group the more reactive it is. Rubidium. The electron affinitiy of chlorine will be similar in magnitude to that of iodine, but chlorine's is higher. Barium oxide is more normally made by heating barium carbonate. 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. Dies geschieht in Ihren Datenschutzeinstellungen. 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.

Dazu gehört der Widerspruch gegen die Verarbeitung Ihrer Daten durch Partner für deren berechtigte Interessen. Atoms of sodium (Na in the table) are larger, and so more reactive, than atoms of lithium (Li in the table). prahalyaa prahalyaa 13.02.2020 Chemistry Secondary School Answer Save. Damit Verizon Media und unsere Partner Ihre personenbezogenen Daten verarbeiten können, wählen Sie bitte 'Ich stimme zu.' 4) Silicon metal will be less reactive than magnesium and aluminum … Once ignited, barium metal burns in air to give a mixture of white barium oxide, BaO, and barium nitride, Ba3N2. Because aluminum replaces compounds of zinc, iron, and copper to produce pure zinc, iron, and copper. Similarly, atoms of potassium (K in the table) are larger, and so more reactive, than atoms of sodium. Relevance. The explanation for this is that rubidium has its single electron farther from the nucleus, where it is more easily removed. Barium, three places below magnesium in the periodic table is more reactive with air than magnesium. Is Rubidium more reactive than Iodine? 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. Answer Save. Under most conditions, aluminum is "more reactive", in the sense that metallic aluminum will replace iron in solution, thus 'precipitating' iron. [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. Log in. Relevance?

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]. The rubidium Pauling electronegativity is 0,82 and the caesium Pauling electronegativity is 0,79; so caesium is more reactive but the difference is not significant. answers The correct anwser is potassium (K)Explanation: Based on its location on the periodic table, which metal is likely to be less reactive than rubidium and more reactive than … Favorite Answer. [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.
