The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
27 sty 2016 · The alkali metals are the elements located in group IA of the periodic table (the first column). The key characteristic these elements share in common is that they all have one electron in the outer electron shell. This lone electron is loosely bound, making this a set of reactive metallic elements. List of the Alkali Metals
The chemistry of the alkali metals depends on the size of the alkali metal cations. The stability of alkali metal compounds depends on the stabilization of their +1 cations. This stability in turn depends on the size of the cations.
The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), [note 1] rubidium (Rb), caesium (Cs), [note 2] and francium (Fr). Together with hydrogen they constitute group 1, [note 3] which lies in the s-block of the periodic table.
29 sie 2023 · Alkali metals are the six different chemical elements found in the first column of the periodic table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr).
30 cze 2023 · This page discusses the trends in some atomic and physical properties of the Group 1 elements - lithium, sodium, potassium, rubidium and cesium. Sections below cover the trends in atomic radius, first ionization energy, electronegativity, melting and boiling points, and density. The chart below shows the increase in atomic radius down the group.
