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 Cd (cadmium) is 48.

Step2: Find the noble gas core

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

Step3: Write the remaining electron configuration

After [Kr], we have 48 - 36 = 12 electrons. The electron configuration for these 12 electrons is \(4d^{10}5s^{2}\)

Answer:

[Kr]4d^105s^2
