Ground State Configuration
* Potassium (K) has an atomic number of 19, meaning it has 19 electrons.
* Its ground state electron configuration is [Ar] 4s¹.
Excited State
* An excited state occurs when an electron absorbs energy and jumps to a higher energy level.
* In potassium, the most likely excited state is when the 4s¹ electron is promoted to the 4p orbital.
* The excited state configuration would then be [Ar] 4s⁰ 4p¹.
Important Note:
* There are actually many possible excited states for potassium, depending on how much energy the electron absorbs and where it moves to. The 4s⁰ 4p¹ configuration is just one example.
* The excited state is not a stable state. The excited electron will eventually lose energy and fall back to the ground state, releasing the absorbed energy as light.
