which is the noble gas notation for chlorine?
ne 4s²4p⁵
ne 3s²3p⁵
ne 3s²3p³
ne 3p²3p⁵

Explanation:

noble gas with the highest atomic number less than 17, with 10 electrons.

Step3: Calculate remaining electrons

$17 - 10 = 7$ electrons left to assign.

Step4: Fill valence orbitals

Fill 3s first (holds 2 electrons), then 3p (holds remaining 5 electrons). This gives $3s^23p^5$.

Step5: Combine core and valence

The full noble gas notation is [Ne] $3s^23p^5$.
