Question

1. look at the model. then, answer the question and choose the best answer.

which energy level has the highest energy?
$n = 3$
$n = 2$
$n = 1$

Explanation:

Step1: Recall energy level concept

In atomic models, as the principal quantum number \(n\) increases, the energy of the electron in that level increases.

Step2: Compare given \(n\) values

We have \(n = 1\), \(n=2\), and \(n = 3\). Since \(3>2>1\).

Answer:

\(n = 3\)
