WebAug 15, 2024 · Group 1: Alkali Metals. A common characteristic of most Alkali Metals is their ability to displace H 2 (g) from water. This is represented by their large, negative electrode potentials. In this event, the Group 1 metal is oxidized to its metal ion and water is reduced to form hydrogen gas and hydroxide ions. WebJan 18, 2024 · Alkali metal oxides are also bases and form alkaline solution when dissolved in water. Group 2 metals also form bases during reaction with water and their oxides are basic and found in earth crust. Be in group 2 is not known as alkaline earth metal because its oxide is amphoteric and are rare.
WebOnly a select number of metal atoms produce flame colors. Most are s-block metals found in group 1 and group 2 of the periodic table. It is not possible to analyze mixtures of compounds using this method, as the flame colors produced by several metals may interfere with each other, giving a misleading result.
