Step 1:I'll solve this problem step by step, carefully following the LaTeX formatting guidelines:
Step 2:: Understand the Electron Configuration
The electron configuration for Potassium (K) is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{1}
Step 3:: Identify Core Electrons
Total core electrons: $$2 + 8 + 8 = 18$$ core electrons
Core electrons are the inner shell electrons that do not participate in chemical bonding. These are the electrons in the completely filled inner shells:
Step 4:: Identify Valence Electrons
Total valence electrons: $$1$$ valence electron
Valence electrons are the electrons in the outermost shell that participate in chemical bonding.
Final Answer
- Core Electrons: 18 - Valence Electrons: 1
