Q
Q: What is the value of the principal quantum number (n) for the outermost electron in potassium (K)?
Solution:
Potassium has the electronic configuration [Ar] 4s1, so the outermost electron is in n=4.
Steps: 5
Show Steps
Step 1: Identify the element in question, which is potassium (K).
Step 2: Look up the atomic number of potassium, which is 19.
Step 3: Determine the electronic configuration of potassium. It is [Ar] 4s1.
Step 4: Analyze the electronic configuration. The '4' in '4s1' indicates the principal quantum number (n) for the outermost electron.
Step 5: Conclude that the value of the principal quantum number (n) for the outermost electron in potassium is 4.
