Explanation / Answer

1.Aufbau principle to obtain the ground-state electronconfiguration of selenium and technetium. selenium( Se ) At . no. of Se is 34 Electronic configuration :1s22s22p63s23p64s23d104p4 technetium ( Tc ) At . no. of Tc is 43 Electronic configuration :1s22s22p63s23p64s23d104p65s2 4d 5
2.-Group the following electronconfigurations in pairs that would represent elements with similarchemical properties: technetium ( Tc ) At . no. of Tc is 43 Electronic configuration :1s22s22p63s23p64s23d104p65s2 4d 5
2.-Group the following electronconfigurations in pairs that would represent elements with similarchemical properties: a) 1s22s22p5 b) 1s22s1 c) 1s22s22p6 d)1s22s22p63s23p5 f)1s22s22p63s23p64s1 g)1s22s22p63s23p64s23d104p6 b) 1s22s1 c) 1s22s22p6 c) 1s22s22p6 d)1s22s22p63s23p5 f)1s22s22p63s23p64s1 g)1s22s22p63s23p64s23d104p6
( a ) & ( d ) show similar chemical properties astheybelongs to VII group ( b) & ( f ) show similar chemical propertiesas theybelongs to I group ( c ) & ( g ) show similar chemicalproperties as theybelongs to zero group 3.- Specify the group of the periodic table in which each ofthe following elements is found: a)[Ne]3s1       ----- IAgroup b) [Ne]3s23p3 ------ V Agroup c) [Ne]3s23p6  ----   O group d)[Ar]4s23d8   ----- O group
