It includes Lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr). The Element Properties: Colorless Odorless Tasteless Electron configuration is 1s1(similar to the electron configurations of group 1 elements) Classified as a non metal Therefore it doesn’t fit into any group. They are called s-block elements because their highest energy electrons appear in the s subshell. GCSE Chemistry (Science) revision covering, elements in Group 1 of the Periodic Table, alkali metals, lithium (Li), sodium (Na), potassium (K). Chemical properties of the group 1 elements Atoms of group 1 elements all have one electron in their outer shell. Group 1: Properties of Alkali Metals This page discusses the trends in some atomic and physical properties of the Group 1 elements - lithium, sodium, potassium, rubidium and cesium. The elements in group 1 are called the alkali metals.. Group 1 is on the left-hand side of the periodic table. and chemical properties. Group 1 elements are known as Alkali Metals. atomic and physical properties of the group 1 elements This page explores the trends in some atomic and physical properties of the Group 1 elements - lithium, sodium, potassium, rubidium and caesium. Table of Data for Group 1 Elements. The alkali metals share similar physical. Group 1 Elements This group lies in the s block of the periodic table. Group 1 elements are very reactive. In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.There are 18 numbered groups in the periodic table; the f-block columns (between groups 3 and 4) are not numbered. You'll find more specific groups, like transition metals, rare earths, alkali metals, alkaline earth, halogens, and noble gasses. This means that the alkali metals all have similar chemical properties . They react with water to produce an alkaline metal hydroxide solution and hydrogen. Physical properties of the alkali metals Group 1 contains elements placed in a vertical column on the far left of the periodic table. Sections below cover the trends in atomic radius, first ionization energy, electronegativity, melting and boiling points, and density. The elements in group 1 are called the alkali metals. Hydrogen The Element H 2 is small and nonpolar so the H atoms can only attract each other chemical reactivity increasing down the group. In this lesson we will learn what types of compounds the group forms, how these compounds are formed, and what these compounds are used for. Chemical properties of Alkali Metals; Uses of Alkali Metals; Group 1 elements are known as Alkali Metals. They are known as s Block Elements as their last electron lies in the s-orbital. Carefully inspect this data to find trends, or patterns, in the properties of group 1 elements. The group 1 elements are all soft, reactive metals with low melting points. There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals. The table below gives the name, atomic number, electronic configuration of the atom, the first and second ionisation energy, melting point, density and electronegativity, of the Group 1 elements (alkali metals). Progressing down group 1, the atomic radius increases due to the extra shell of electrons for each element.
