Question

question 36 (2 points)
how many electrons are in the highest occupied energy level of a neutral chlorine atom?
blank 1:

Explanation:

Step1: Determine the electron configuration of chlorine

Chlorine (Cl) has an atomic number of 17. The electron configuration is \(1s^{2}2s^{2}2p^{6}3s^{2}3p^{5}\).

Step2: Identify the highest - occupied energy level

The highest - occupied energy level is the third energy level (\(n = 3\)).

Step3: Count the electrons in the highest - occupied energy level

In the third energy level (\(n=3\)), there are \(2\) electrons in the \(3s\) sub - shell and \(5\) electrons in the \(3p\) sub - shell. The total number of electrons in the \(n = 3\) energy level is \(2 + 5=7\).

Answer:
