Question

A) write the abbreviated electron configuration for bismuth(Pb)

B) write the abbreviated electron configuration for a iodide ion.

Answer 1

Answer sd A Bi is a P-block element with period number 6 and group number 15. Hence Principal quantum number of valence shell of Bi is 6. Also, Bi has c. filled af and orbital and half- filled 68 orbital electronic configuration : [xe] 4614 5d 65² 6P3 ([xe] represents electronic configuration of inner shells which is same with electronic configuration of xe) 6 is a p-block element with period number 5 and group number 17. Hence principal quantum number of valence shell of I is 5. Also, I has filled 4d orbital and partially filled 5p orbital with 5 electrons. electronic configuration of I: [ko] 4d10 55²5ps so the extra electron in I (iodide ion will be added into sp orbital giving same electronic configuration as with xe. electronic configuration of I: [kr] 4 do 55² 506
