Question

the periodic table has a different number of electrons and orbitals that fill in a set order. each element of the periodic table has a different number of electrons and, therefore, a different electron configuration.
part d
cs
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

Cesium (Cs) has an atomic number of 55. The noble gas with an atomic number less than 55 is Xenon (Xe) which has an atomic number of 54.

Step2: Write the remaining electrons

After the [Xe] core, there is 1 electron left. This electron goes into the \(6s\) orbital.

Answer:

[Xe]6s^1
