1.-Write ht eground state electron configurations of thefollowing ions, which lay important roles in biochemical processesin our bodies: a) Na+, b) Mg2+, c)Cl-, d) K+, e) Ca2+, f)Fe2+, g) Cu2+, h) Zn2+ 2.- Indicate which one of the two species in each of thefollowing pairs is smaller: a) Cl or Cl-; b) Na orNa+; c) O2- or S2-; d) Mg2+or Al3+; e) Au+ orAu3+. 3.- Explain which of the following cations is larger, and why:Cu+ or Cu2+; also which of the followinganions is larger and why: Se2- or Te2-. 1.-Write ht eground state electron configurations of thefollowing ions, which lay important roles in biochemical processesin our bodies: a) Na+, b) Mg2+, c)Cl-, d) K+, e) Ca2+, f)Fe2+, g) Cu2+, h) Zn2+ 2.- Indicate which one of the two species in each of thefollowing pairs is smaller: a) Cl or Cl-; b) Na orNa+; c) O2- or S2-; d) Mg2+or Al3+; e) Au+ orAu3+. 3.- Explain which of the following cations is larger, and why:Cu+ or Cu2+; also which of the followinganions is larger and why: Se2- or Te2-. 2.- Indicate which one of the two species in each of thefollowing pairs is smaller: a) Cl or Cl-; b) Na orNa+; c) O2- or S2-; d) Mg2+or Al3+; e) Au+ orAu3+. 3.- Explain which of the following cations is larger, and why:Cu+ or Cu2+; also which of the followinganions is larger and why: Se2- or Te2-.Explanation / Answer
( 1 ) Na + ( 10) : Electronic configuration :1s22s22p6 Mg 2+ ( 10) : Electronicconfiguration :1s22s22p6 Cl - ( 18) : Electronicconfiguration :1s22s22p63s23p6 K + ( 18 ) : Electronic configuration :1s22s22p63s23p6 Ca 2+ ( 18 ) : Electronic configuration :1s22s22p63s23p6 Fe 2+ (24) : Electronic configuration :1s22s22p63s23p64s03d6 Cu 2+ (27) : Electronic configuration :1s22s22p63s23p64s13d9 Zn 2+ (228) : Electronic configuration :1s22s22p63s23p64s03d10 2.- Indicate which one of the two species in each of thefollowing pairs is smaller: a) Cl or Cl- --------- Cl is smallest,Since the nulear charge on Cl & Cl - is same and Cl has 17 e -& Cl - has 18 e - But the effective nuclear charge on Cl is more . b) Na or Na+ ------ Na + issmallest , Since the nulear charge on Na & Na+ is same and Na has 11 e - &Na + has10e- But the effective nuclear charge on Na + is more . c) O2- or S2- -------- O2- is smallest.Since Onmoving from top to bottom the size will increases. d) Mg2+ or Al3+ ------ Al3+ ,Mg2+ have same number of electronsi.e., 10 but among them Al 3+ has moreeffective nuclear charge there by its size will be less thanMg2+ e) Au+ or Au3+ ------ Au3+ is smallest 3.- Explain which of the following cations is larger Cu+ or Cu2+ ----- Cu+ is larger .Since on removingone more electron from Cu+ the the effectivenuclear charge on Cu2+ will increases there by it will sink insize Se2- or Te2-.------- Te2- is larger in size .Since both belongs to thesame group & on moving from top to bottom the size will increases.
