They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution. All the alkali metals react vigorously with halogens to produce salts, the most industrially important of which are NaCl and KCl. These cations are respectevely: Ag + , Pb 2+ , Hg 2 2+ . Group-1-Reactions. Start studying Group 1 Cations & Reactions. The Group 1 elements in the periodic table are known as the alkali metals. Group-1-Reactions. £1.50. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution. For similar reasons the electronegativity decreases. About this resource. Start studying Group 1 Anions (Reagents + Reactions). 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. Reactions of the Group 1 hydrides. The Group 1 elements in the periodic table are known as the alkali metals. Learn vocabulary, terms, and more with flashcards, games, and other study tools. It is all around us. Group 1: The Alkali Metals. It is, however, possible to melt lithium hydride and to electrolyse the melt. Categories & Ages. Report a problem. The Reactions with Oxygen. Info. Group 1 cations includes those cations who selectively precipitates as chlorides by addition of diluted hydrochloric acid. Read more. Generally the melting point of the alkali metals decreases down the group. The Reactions of the elements with Chlorine. 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. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
