Question

cd
express your answer in condensed form in order of increasing orbital energy as a string without blank space between orbitals. for example, he2s²2p² should be entered as he2s^22p^2.

Explanation:

Step1: Determine the atomic number of Cd

The atomic number of cadmium (Cd) is \(48\).

Step2: Find the noble gas core

The noble gas before Cd is Kr (atomic number \(36\)).

Step3: Write the electron configuration for the remaining electrons

After \(Kr\), we have \(48 - 36=12\) electrons. The electron configuration for these electrons is \(4d^{10}5s^{2}\) (using the Aufbau principle, Pauli exclusion principle and Hund's rule).

Answer:

$$ [Kr]4d^{10}5s^{2} $$

In the required string format: \([Kr]4d^{\wedge}105s^{\wedge}2\)
