5.(18ps) (a) 6pts. What is the ground state electron configuration and orbital d

Question

5.(18ps) (a) 6pts. What is the ground state electron configuration and orbital diagram of Ta(73)? Is this paramagnetic or diamagnetic? (b) 4pts. The following is an excited state configuration of a neutral atom: 1s 2s 2p 3s 4s'3d10 4p* 5s' Identify the element and write its ground state electronic configuration Is this excited state diamagnetic or paramagnetic? Explain (c) 8pts, Write the ground state electron configuration of each of the following ions: (i)Mn2 (25) ii) Rh (45)i) Pt2 (78) (iv) As (33)

Explanation / Answer

this the ground state electron configuration of tantalum

1s22s22p63s23p63d104s24p64d105s25p64f145d36s2 or [Xe] 4f145d36s2

you have 5 d3 orbitals d can hold up to 10 electrons in 5 pairs

you have 3 electrons and these are unpaired so this makes it a paramagnetic material
