WebIn this practical, students observe what happens when three Group 1 metals are heated in air and in chlorine. The experiment can be used as preparation for demonstrating the … WebAll group 1 metals react vigorously with chlorine gas forming white salts or colourless crystals known as metal chlorides. Below is a generic formula that represents the alkali metals (X) reacting with chlorine: 2 X (s) + Cl 2 (g) → 2 XCl (s) All alkali metals have 1 electron in their outermost shell.

WebNov 30, 2024 · General physical properties of Group 1 elements: Alkali metals are grey solidswith shiny silvery surfaceswhen freshly cut. These surfaces turn dullwhen exposed to air. This is because alkali metals are very reactive. They react rapidly with oxygen and water vapour in the air when exposed. Alkali metals are soft solidsand can be easily cut. WebJul 4, 2024 · For these reasons, the group 1 elements were unknown until the early 19th century, when Sir Humphry Davy first prepared sodium (Na) and potassium (K) by passing an electric current through molten alkalis.
