Current Question (ID: 7631)

Question:

$\text{The electronic configuration of Palladium is:}$

Options:

1. $[\text{Kr}] 5\text{f}^3 6\text{d}^1 7\text{s}^2$
2. $[\text{Kr}] 5\text{f}^5 6\text{d}^1 7\text{s}^2$
3. $[\text{Kr}] 5\text{f}^2 6\text{d}^1 7\text{s}^2$
4. $\text{None of the above.}$ (Correct)

Solution:

$\text{HINT: Palladium is a d-block element.}$\n\n$\text{Explanation:}$\n\n$\text{The condensed electronic configuration of Pd is as follows:}$\n\n$\text{Pd}_{46} = [\text{Kr}]_{36} 4\text{d}^{10}$\n\n$\text{The above is the configuration of palladium metal with a complete valence 4d-shell.}$\n\n$\text{The complete electronic configuration of Palladium}$\n$\text{(46):}1\text{s}^2,2\text{s}^2,2\text{p}^6,3\text{s}^2,3\text{p}^6,4\text{s}^2,3\text{d}^{10},4\text{p}^6,5\text{s}^0,4\text{d}^{10}$
