Question

part d
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 noble gas core

Cadmium (Cd) has an atomic number of 48. The noble gas that comes before Cd in the periodic table is Kr (krypton) with an atomic number of 36.

Step2: Write the remaining electron configuration

After the Kr core, we have 12 more electrons. The electron - filling order after Kr is \(4d^{10}5s^{2}\)

Answer:

[Kr]4d^105s^2
