Question

11. Sketch the electron configuration diagram for the element from Group 5 and Period 4 with its most common ionic charge. Is this paramagnetic or diamagnetic? 12. Write out a) the full spdf notation and b) the shorthand notation for the electron configuration of technetium. Ansat b)

Answer 1

1. The Group 5 period A element is Vanadium (V). Atomic no. of Vanadium = 23 Electronic configuration 15 2 252 2p 3s? 3p6 45² z 23. The most common lonie form of ranadium is ve . Electronic configuration - 187 288 2p6 38 ~ 3p64 gozd The four electrons of left by vanadium first 2 form as as it is the outermost orbital Then 2 electrons forr from 3d as it has the highest energy of among 3p and Is, and 3d. 9 As it has a 1 unpaired electron so it is paramagnetic 2. Techretium - 43 lay 1s? 28%256 357 3p645" 3 dº 4p6 55*4d54fº. (6) Kv - is" 252p635*3p6 45" 34'0 4p6 Hence shorthand electronic configuration = [kr]55 445
