Question

write the condensed (noble - gas) electron configuration of cl. for multi - digit superscripts or coefficients, use each number in succession. henearkrxern 1 2 3 4 5 6 s p d f

Explanation:

Step1: Determine the atomic number of Cl

The atomic number of Cl (chlorine) is 17.

Step2: Find the nearest noble - gas with a lower atomic number

The nearest noble - gas with a lower atomic number than 17 is Ne (neon) which has an atomic number of 10.

Step3: Write the electron configuration after the noble - gas

After [Ne], we need to account for \(17 - 10=7\) more electrons. The next sub - shells are \(3s\) and \(3p\). The \(3s\) sub - shell can hold 2 electrons and the \(3p\) sub - shell can hold 5 electrons.

Answer:

\([Ne]3s^{2}3p^{5}\)
