Q80E. Which of the following atoms and... [FREE SOLUTION]

Chapter 6: Q80E. (page 338)

Which of the following atoms and ions is (are) isoelectronic with\({{\bf{S}}^{{\bf{2}} + }}:{\rm{ }}{\bf{S}}{{\bf{i}}^{4 + }}{\rm{ ,}}{\bf{C}}{{\bf{l}}^{{\bf{3}} + }},{\rm{ }}{\bf{Ar}},{\rm{ }}{\bf{A}}{{\bf{s}}^{{\bf{3}} + }},{\rm{ }}{\bf{Si}},{\rm{ }}{\bf{A}}{{\bf{l}}^{{\bf{3}} + }}\)?

Short Answer

Expert verified

\(C{l^{3 + }}\) and Si are isoelectronic with \({S^{2 + }}\).

Step by step solution

Isoelectronic species

An atom is isoelectronic with another if they both have the same electronic configuration. In other words, isoelectronic atoms/ ions are atoms with the same electron configuration.

Atoms/ ions which are isoelectronic with \({\bf{B}}{{\bf{r}}^ + }\;\)

Configuration of S²⁺includes configuration of (Si). So, we need to check the atoms have the configuration of (Si). Among the given atoms/ ions Cl³⁺and Si have the configuration of (Si). Hence, \({\bf{C}}{{\bf{l}}^{{\bf{3}} + }}\)and Si are isoelectronic with \({{\bf{S}}^{{\bf{2}} + }}\).
