  • The alkali metals are the elements in Group 1 of the periodic table. These include lithium, sodium, potassium, rubidium, caesium and francium.
  • (What elements are included in this group of elements?)
  • Alkali Metal is the name given to the first group of elements in the Periodic Table. They have 1 valence electron and thus, valency +1. All of the alkali merals are metals as they lose electron to form cations. They form basic oxides. Francium is the most metallic element both in group and the periodic table.

abstract
  • The alkali metals are the elements in Group 1 of the periodic table. These include lithium, sodium, potassium, rubidium, caesium and francium.
  • (What elements are included in this group of elements?)
  • Alkali Metal is the name given to the first group of elements in the Periodic Table. They have 1 valence electron and thus, valency +1. All of the alkali merals are metals as they lose electron to form cations. They form basic oxides. Francium is the most metallic element both in group and the periodic table. Among the alkali metals sodium and potassium are abundant and lithium, rubidium and cesium have much lower abundances. Francium is highly radioactive; its longest-lived isotope 223Fr has a half-life of only 21 minutes. The general electronic configuration of Alkali metals is [Noble Gas]ns1.
