Question: Which of the following elements has the highest energy level in its electronic configuration?

Options:

Correct Answer: K

Solution:

Potassium (K) has the highest energy level with the configuration [Ar] 4s1.

Which of the following elements has the highest energy level in its electronic configuration?

Which of the following elements has the highest energy level in its electronic configuration?

Step 1: Understand that the energy level of an element is determined by its electron configuration.
Step 2: Identify the electron configuration of each element given in the question.
Step 3: Look for the highest principal quantum number (n) in the electron configurations. This number indicates the energy level.
Step 4: Compare the principal quantum numbers of the elements. The element with the highest n value has the highest energy level.
Step 5: For Potassium (K), the electron configuration is [Ar] 4s1, where '4' is the highest principal quantum number.
Step 6: Conclude that Potassium (K) has the highest energy level among the options provided.
