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 noble gas core

Cadmium (Cd) has an atomic number of 48. The noble gas before Cd is Kr (atomic number 36).

Step2: Write the electron configuration after the noble gas core

After [Kr], we fill the 4d and 5s orbitals. The 4d orbital has 10 electrons and the 5s orbital has 2 electrons.

Answer:

[Kr]4d^105s^2
