Alkali metals include hydrogen, lithium, sodium and potassium. This gets close to the reason why "metals" is not included in this proposal. The alkali metals can be found in the first column on the left side of the Periodic Table. All the metals in the periodic tables are classified into three groups, namely; alkali metals, alkaline earth metals, and transition metals. This group lies in the s-block of the periodic table of elements as all alkali metals have their outermost electron in an s-orbital: this element/electron configuration results in their characteristic properties. Both Li and Na salts are used as drying agents, compounds that are used to absorb water. The elements in group one of the periodic table (with the exception of hydrogen - see below) are known as the alkali metals because they form alkaline solutions when they react with water. Alkali metals alloys are either liquids or solids within a solution. 7. The mobilities of the alkali metal ions in aqueous solution are; Li + < Na + < K + < Rb + < Cs + (b) Lithium is the only alkali metal to form a nitride directly. Metals can also be divided into Base metal, Noble metal, Ferrous metal and Precious metal. Is lithium metal heavier or lighter than water? Alkali metal ferrite is also produced as a product and is subjected to reaction with water to produce ferric oxide and the alkali metal hydroxide used in the first reaction. They form basic oxides. 8th - 10th grade. Stored in a mineral oil solution. Alkali Metals DRAFT.
