Question
Match each element with the full ground-state electron configuration of the monatomic ion it is most likely to form. (Enter the 6 correct letters, in order: BABCEG, FBAGCC, etc.).... If you could explain what the monatomic part means I would really apreciate it, because I understand how you would do this question without that on there.
1) Cl A. 1s22s22p63s23p6 2) Rb B. 1s22s22p6 3) F C. 1s22s22p63s23p64s23d104p65s1 4) O D. 1s22s22p4 5) S E. 1s2 6) P F. 1s22s22p63s23p4 G. 1s22s22p63s23p64s23d104p6Explanation / Answer
(1)The electronic configuration of Cl (At.No. 17 ) is : 1s2 2s2 2p6 3s2 3p5
On adding one electron to Cl atom we get Cl- & its configuration is 1s2 2s2 2p6 3s2 3p6
(2)The electronic configuration of Rb (At.No. 37 ) is : 1s2 2s2 2p6 3s2 3p5 3d10 4s2 4p6 5s1
On removing one electron to Rb atom we get Rb+ & its configuration is 1s2 2s2 2p6 3s2 3p5 3d10 4s2 4p6
(3)The electronic configuration of F (At.No. 9 ) is : 1s2 2s2 2p5
On adding one electron to F atom we get F- & its configuration is 1s2 2s2 2p6
(4)The electronic configuration of O (At.No. 8 ) is : 1s2 2s2 2p4
On adding one electron to O atom we get O- & its configuration is 1s2 2s2 2p5
(5)The electronic configuration of S (At.No. 16 ) is : 1s2 2s2 2p6 3s2 3p4
On adding one electron to S atom we get S- & its configuration is 1s2 2s2 2p6 3s2 3p5
(6)The electronic configuration of P (At.No. 15 ) is : 1s2 2s2 2p6 3s2 3p3
On adding one electron to P atom we get P- & its configuration is 1s2 2s2 2p6 3s2 3p4
monoatomic part is the ion which is most stable than the actual element when adding or removing one electron.
The given configurations are wrong ( some one)
