Elements that are alkali metals

WebJul 20, 2024 · Li, Na, K, Rb, and Cs are all group IA elements, also known as the alkali metals. The seventh member of the group, francium (Fr) is radioactive and so rare that only 20 atoms of Fr may exist on Earth at any given moment [1]. The term alkali is derived from an Arabic word meaning “ashes.” WebAlkali Metals. Lithium, sodium, potassium, rubidium, cesium, and francium are all alkali metals belonging to the periodic table’s Group 1 element. The name alkali metals come from their reactivity with water. Due to the high reactivity, alkali metals are frequently found in nature with other elements.

WebNov 30, 2024 · 2. General physical properties of Group 1 elements: Alkali metals are grey solids with shiny silvery surfaces when freshly cut. These surfaces turn dull when 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 solids and can be easily cut. The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table. All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties.
