Web1 Feb 2024 · The alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). This group lies in the s-block of the periodic table, as all alkali metals have their outermost electron in an s-orbital. The alkali metals provide the best example of group trends in properties in the periodic table, with elements ... WebIonization Energy: The amount of energy required to eject an electron from an atom is known as ionization energy. The amount of ionization energy depends on the size of the atoms and the distance of the electron from the nucleus. Electrons in a shell are held in position by the force applied by the protons that lie inside the nucleus.
