The group 1 elements are all soft, reactive metals with low melting points. Group 1 elements are known as Alkali Metals. You'll find more specific groups, like transition metals, rare earths, alkali metals, alkaline earth, halogens, and noble gasses. 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 doesnât fit into any group. Table of Data for Group 1 Elements. There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals. They react with water to produce an alkaline metal hydroxide solution and hydrogen. GCSE Chemistry (Science) revision covering, elements in Group 1 of the Periodic Table, alkali metals, lithium (Li), sodium (Na), potassium (K). It includes Lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr). Carefully inspect this data to find trends, or patterns, in the properties of group 1 elements. 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. 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. chemical reactivity increasing down the group. Sections below cover the trends in atomic radius, first ionization energy, electronegativity, melting and boiling points, and density. 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. The elements in group 1 are called the alkali metals. The alkali metals share similar physical. This group lies in the s block of the periodic table. and chemical properties. This means that the alkali metals all have similar chemical properties . Chemical properties of the group 1 elements Atoms of group 1 elements all have one electron in their outer shell. 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. They are known as s Block Elements as their last electron lies in the s-orbital. Chemical properties of Alkali Metals; Uses of Alkali Metals; Group 1 elements are known as Alkali Metals. Physical properties of the alkali metals Group 1 contains elements placed in a vertical column on the far left of the periodic table. Progressing down group 1, the atomic radius increases due to the extra shell of electrons for each element. The elements in group 1 are called the alkali metals.. Group 1 is on the left-hand side of the periodic table. Group 1 Elements Group 1 elements are very reactive. Hydrogen The Element H 2 is small and nonpolar so the H atoms can only attract each other They are called s-block elements because their highest energy electrons appear in the s subshell. 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).
