how many electrons are in the highest occupied energy level of copper?
blank 1:

Explanation:

Step1: Write the electron configuration of copper

Copper (\(Cu\)) has an atomic number of \(29\). Its electron configuration is \([Ar]3d^{10}4s^{1}\).

Step2: Identify the highest - occupied energy level

The highest - occupied energy level is the \(4^{th}\) energy level (\(n = 4\)). In the \(4s\) sub - level (part of the \(n = 4\) energy level), there is \(1\) electron.

Answer:

\(1\)
