The home learning ideas explain how learners can explore the reactions of these metals without access to a science lab.

Nonmetals, in contrast, are generally poor conductors of heat and electricity and are not lustrous. This Alkali Metals lesson pack helps KS3 Science learners to identify the alkali metals on the periodic table and describe the patterns in alkali metal properties as you move down Group 1. Alkali metals These are known as s-block elements as their outermost orbitals are s and only one electron is present in it. Of the metals, only mercury is a liquid at room temperature and pressure all the rest are solids. The elements of group I-A except hydrogen whose oxides and hydroxides are strong alkalies are called alkali metals. They all have one valence electron in the outermost shell which they seek to lose in. Francium is a radioactive element with very low half-life. The alkaline earth metals are found on the periodic table in Group 2, which is on the far left side of the table between Group 1, the alkali metals, and Groups. Alkali elements are Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Ru), Cesium (Cs) and Francium (Fr) occupying successive periods from first to seven. They occupy the first column of the periodic table. The vast majority of the known elements are metals. Alkali Metals They are shiny, soft, metals. Alkali metals have a corresponding Noble gas ns 1 electronic configuration. Metals-such as copper or gold-are good conductors of electricity and heat they can be pulled into wires because they are ductile they can be hammered or pressed into thin sheets or foils because they are malleable and most have a shiny appearance, so they are lustrous. The distinction between metals and nonmetals is one of the most fundamental in chemistry. Gold-colored lements that lie along the diagonal line exhibit properties intermediate between metals and nonmetals they are called semimetals. \) divides the elements into metals (in blue, below and to the left of the line) and nonmetals (in bronze, above and to the right of the line).
