electrons - Why are these ions classified as isoelectronic?

Web15 jun. 2012 · For the first-row main-group element boron, which resists multiple bonding in general and forms triple bonds to other elements only very rarely (4–7), the synthetic challenge of preparing a stable B-B triple bond has thus far been prohibitive.In 2002 the molecule OCBBCO, ostensibly a B 2 molecule stabilized by two Lewis bases, was … WebAtoms and ions that have the same electron configuration are said to be isoelectronic. Examples of isoelectronic species are N3–, O2–, F–, Ne, Na+, Mg2+, and Al3+ (1s22s22p6). Another isoelectronic series is P3–, S2–, Cl–, Ar, K+, Ca2+, and Sc3+ ([Ne]3s23p6). For atoms or ions that are isoelectronic, the number of protons … WebUsing a quadratic Z-dependence of mean excitation energies in isoelectronic series, we have estimated mean excitation energies of some of the more highly charged cations of K, Ca, Ga, Ge, As, Se, Br and Kr. Also estimated values for the mean excitation energies of singly, negatively charged ions of 3d-elements are reported. chuck e cheeses band
