Q: What is the value of the principal quantum number for the outermost electrons in a sodium atom?
Solution:
Sodium has an atomic number of 11, and its outermost electrons are in the n=3 shell.
Steps: 5
Show Steps
Step 1: Identify the atomic number of sodium, which is 11.
Step 2: Understand that the atomic number tells us the number of electrons in a neutral sodium atom, which is also 11.
Step 3: Determine the electron configuration of sodium. The configuration is 1s² 2s² 2p⁶ 3s¹.
Step 4: Look at the outermost electrons in the electron configuration. The outermost electrons are in the 3s subshell.
Step 5: Identify the principal quantum number (n) for the outermost electrons. For the 3s subshell, n = 3.
