Question

13. what is the noble gases that has the same electron configuration as each of the ions in the compound formed for Z = 20 and Z= 16

. 14. predict and explain which of the following pair has the more polar bonds : CL-1 OR CL-AS

15.EXPLAIN WHY THE MOLECULAR STRUCTURE OF OXYGEN DIFLORIDE IS NONLINEAR WHILE FOR BERYLLIUM FLOORIDE IS LINEAR?

22. PREDICT THE Z NUMBER OF THE LARGEST ATOM IN GROUP (COLUMN) 2 AND EXPLAIN YOUR PREDICTION

23. EXPLAIN HOW THE ATTRACTION AND NUCLEUS EXERTS ON ELECTRONS CHANGES WITH THE PRINCIAL ENERGY (N) OF THE ELECTRON.

9. DRAW THE LEWIS STRUCTURE FOR THE COMPOUND FORM FROM ELEMENT Z=16AND Z=14. WHAT WOULD THE GEOMENTRY OF THIS MOLECULE BE?

From Z = 20 i.e. Ca atom on ionization of 2 e– a cation Zn2+ forms having 18 e– which corresponds to the Argon (Ar) noble metal.

Ground state electronic configuration of Ca : 1s2 2s2 2p6 3s2 3p6 3d0 4s2.

Ground state electronic configuration of Ca2+: 1s2 2s2 2p6 3s2 3p6 3d0 4s0.

Which is isoelectronic with Argon (Ar)

And

From Z = 16 i.e. Sulfur S atom on accepting 2e– forms S2– ion having 18 e– which also corresponds to the Argon noble metal.

Ground state electronic configuration of S: 1s2 2s2 2p6 3s2 3p4 3d0

Ground state electronic configuration of S2–: 1s2 2s2 2p6 3s2 3p6 3d0

Which is isoelectronic with Argon (Ar)
