Question

cs express your answer in condensed form in order of increasing orbital energy as a string without blank spaces between orbitals. for example, he2s^22p^6 should be entered as he2s^22p^6.

Explanation:

Step1: Identify noble gas core

Cesium (Cs) is in period 6, so the preceding noble gas is Xenon (Xe), with electron configuration represented as [Xe].

Step2: Add valence electrons

Cs has 1 valence electron in the 6s orbital, so we add $6s^1$ to the noble gas core.

Answer:

[Xe]6s^1
