Step 1:I'll solve this step by step with proper LaTeX notation:
Step 2:: Understand Lithium's Atomic Structure
- Lithium is the third element in the periodic table - Its atomic number is 3, meaning it has 3 electrons - Electrons fill orbitals according to the Aufbau principle
Step 3:: Electron Filling Order
- Electrons first fill the 1s orbital - The 1s orbital can hold a maximum of 2 electrons - After 1s is filled, electrons begin to fill the 2s orbital
Final Answer
The correct electron configuration for lithium is
