Core electrons shield valence electrons so that they experience an effective nuclear charge zeff rather than the full nuclear charge. given that the first ionization energy of be is 9.32 ev, use the formula en=βz2e2/(8ΟΞ΅0a0n2), n=1,2,3, to estimate the effective nuclear charge experienced by the 2s electron in be. e=1.602Γ10β19c, me=9.109Γ10β31kg, Ξ΅0=8.854Γ10β12c2β jβ1β mβ1, h=6.626Γ10β34jβ s.
