Answer 1

Which of the following symbols would be included in the noble gas notation for an element that had valence electrons in the 5s subshell?

Kr

hope this helps.

Answer 2

Kr in Xe = [Kr]4d¹⁰5s²5p⁶

Step-by-step explanation:

The noble gas that has electron in 5s orbital are Xe and Rn. But however, for the purpose of this question, I'll stick with Xe. The electronic configuration of Xe is 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶ or [Kr]4d¹⁰5s²5p⁶
