Categories & Ages. Group-1-Reactions. Reactions of Group 1 Elements with Water; Reactions of Group I Elements with Chlorine; Reactions of Group I Elements with Oxygen; Chemistry of Hydrogen (Z=1) Hydrogen is one of the most important elements in the world. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution. Report a problem. Chemistry; Start studying Group 1 Anions (Reagents + Reactions). The Group 1 elements in the periodic table are known as the alkali metals. Generally the melting point of the alkali metals decreases down the group. This is because as the ions get larger the distance between the bonding electrons and the positive nucleus gets larger and reduces the overall attraction between the two. The Group 1 elements in the periodic table are known as the alkali metals. These are limited to the two reactions most likely to be wanted by UK A level syllabuses. It is, however, possible to melt lithium hydride and to electrolyse the melt. Sodium, for example, burns with an intense orange flame in chlorine in … This is included on this page because of the similarity in appearance between the reactions of the Group 1 metals with chlorine and with oxygen. All the alkali metals react vigorously with halogens to produce salts, the most industrially important of which are NaCl and KCl. About this resource. Info. Group-1-Reactions. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution. It is all around us. Group 1: The Alkali Metals. On heating, most of these hydrides decompose back into the metal and hydrogen before they melt. £1.50. The Reactions of the elements with Chlorine. Loading... Save for later. Reactions of the Group 1 hydrides. Table worksheet for Group 1 reactions with water and oxygen for GCSE Chemistry. The reactions of the Group 1 elementrs with chlorine are similar in appearance to the reactions of the Group 1 metals with oxygen.Sodium, for example, burns with an intense orange flame in chlorine in … Group 1 metals are very reactive, and must be stored out of contact with air to prevent oxidation. Electrolysis. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Created: Nov 5, 2020. pptx, 44 KB. Start studying Group 1 Cations & Reactions.
