Step 2:: Identify the Atomic Number
Beryllium has an atomic number of 4, which means it has 4 electrons to distribute in its electron configuration.
Step 3:: Determine the Electron Shell Filling Order
Electrons fill orbitals following the Aufbau principle, which means they fill from lowest energy levels to higher energy levels.
Step 4:: Write the Electron Configuration
- $$2s^{2}$$: Second shell (2 electrons)
The electron configuration for beryllium will be: Breakdown:
Step 5:: Verify Total Electron Count
- $$1s^{2}$$: 2 electrons
- 2s^{2}: 2 electrons Total: 4 electrons ✓
Final Answer
The electron configuration of beryllium is 1s^{2} 2s^{2}.
