Molar ionization energies of the elements - Wikipedia

WebThe alkali metals are so reactive, due to a number of factors. Their low first ionization energy, combined with the fact they have just 1 electron to donate to get to a stable full shell state, makes them so reactive – even more so as their atomic radium gets larger. Fun or interesting facts about the Alkali Metals WebIonization energy, also called ionization potential, is the energy necessary to remove an electron from the neutral atom. X + energy → X+ + e− where X is any atom or molecule capable of being ionized, X + is that atom or molecule with an electron removed (positive ion), and e − is the removed electron. WebIn general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. This pulls the electron cloud closer to the nucleus, strengthening the nuclear attraction to the outer-most electron, and is more difficult to remove (requires more energy). strong swiss cheese
