Web26 mei 2024 · The energy needed to remove an electron from an element is called the first ionization energy. The alkali metals have the lowest first ionization energies of all of the elements. WebAs with the alkali metals of Group 1 (Ia), the atoms of the alkaline-earth metals easily lose electrons to become positive ions (cations). Most of their typical compounds are therefore ionic: salts in which the metal occurs as the cation M 2+, where M represents any Group 2 …
WebSolution. Across a period, the screening effect is the same while the effective nuclear charge increases. As a result, the outer electron is held more tightly, and hence, the ionization … WebThe heavier alkaline earth metals react more vigorously than the lighter ones. The alkaline metals have the second-lowest first ionization energies in their respective periods of the periodic table. This is due to their low effective nuclear charges and the ability to attain a full outer shell configuration by losing just two electrons. The ...
