To determine: The first-row two elements that have unexpected electron configurations; the reason behind the absence of
Answer to Problem 1RQ
Answer
The two metals that have unexpected electron configuration are chromium and copper.
Due to less effect of effective nuclear charge over
Due to the less energy gap between the
Explanation of Solution
Explanation
The expected electronic configuration of chromium is represented as,
The actual electronic configuration of chromium is represented as,
The expected electronic configuration of copper is represented as,
The actual electronic configuration of chromium is represented as,
The half filled and fully filled orbital are more stable. Therefore to attain stability, these metals attain the unexpected configuration.
Due to less effect of effective nuclear charge over
The effect of effective nuclear charge over
Due to the less energy gap between the
The electrons in transition metal atom are present in
Conclusion
Transition metal atoms exhibit properties between
