Question
34. What is the noble gas configuration for potassium?
1 point
- [Kr] 4s²
- [Kr] 4s¹
- [Ar] 4s¹
- [Ar] 4s²
Solution
The noble gas configuration for potassium is [Ar] 4s^1.
Here's the step by step process:
-
Identify the atomic number of potassium. Potassium (K) has an atomic number of 19.
-
Find the noble gas that comes before potassium in the periodic table. The noble gas that comes before potassium is Argon (Ar), which has an atomic number of 18.
-
Write the electron configuration for potassium. The electron configuration for potassium is [Ar] 4s^1. This means that potassium has the same electron configuration as Argon, plus one electron in the 4s orbital.
