Question

where each orbital is denoted by a box and each electron is denoted by a half arrow Anomalous electron configurations Some atoms, such as some transition metals and some elements in the lanthanide and actinide series, do not adhere strictly to Hund's rule and Paul's and completely filled subshells This behavior can be explained with an example of the chromium atom. Using Hund's rule and Paulis principle, you can write the expected electron co 182 282 2ps 3s 3p6 43d. However, by moving an electron from the 4s orbital to the 3d otbital you obtain a halif filed 3d orbital. This haif-fled orbital. Thus, the observed electron configuration of the Cr atom is 1s2 2s2 2p6 3s2 3p6 4s1 3d Part D Pd has an anomalous electron configuration. Write the observed electron configuration of Pd Express your answer in complete form in order of orbital filling. For example, 1s2 2s2 should be entered as 1s-22-2 Hints Submit My Answers Give Up MacBook Air

Explanation / Answer

Pd have atomic no. 46 contain 46 electron

elctron filling take place according to icreasing energy level but in Pd first filled 4d orbital and 5s orbital is empty

electronic configuration of Pd are as given below

46Pd = 1s22s22p63s23p64s23d104p65s03d10

this electronic configuration because

1.Full d orbital is more stable than partially filled one

2.At higher energy level, level are said to be degenarated which mean that thay have very close energy and electron can jump from one orbital to another esily
