Question

Choose the correct option having all the elements with \( d^{10} \) electronic configuration from the following:

• A. \( {}^{27}\text{Co}, {}^{28}\text{Ni}, {}^{26}\text{Fe}, {}^{24}\text{Cr} \)
• B. \( {}^{29}\text{Cu}, {}^{30}\text{Zn}, {}^{48}\text{Cd}, {}^{47}\text{Ag} \)
• C. \( {}^{46}\text{Pd}, {}^{28}\text{Ni}, {}^{26}\text{Fe}, {}^{24}\text{Cr} \)
• D. \( {}^{28}\text{Ni}, {}^{24}\text{Cr}, {}^{26}\text{Fe}, {}^{29}\text{Cu} \)

Answer 1

The Correct Option is B

Elements such as Cu, Zn, Ag, and Cd exhibit a \(d^{10}\) electronic configuration:

- \([ \text{Cu} ] = [ \text{Ar} ] 3d^{10} 4s^1\),
- \([ \text{Zn} ] = [ \text{Ar} ] 3d^{10} 4s^2\),
- \([ \text{Ag} ] = [ \text{Kr} ] 4d^{10} 5s^1\),
- \([ \text{Cd} ] = [ \text{Kr} ] 4d^{10} 5s^2\).

The Correct answer is: \( {}^{29}\text{Cu}, {}^{30}\text{Zn}, {}^{48}\text{Cd}, {}^{47}\text{Ag} \)
