1. Electron Configuration:
* Boron has an atomic number of 5, meaning it has 5 electrons.
* Its electron configuration is 1s² 2s² 2p¹
2. Orbitals:
* 1s orbital: This is the lowest energy level and can hold a maximum of 2 electrons.
* 2s orbital: This is the next energy level and can also hold a maximum of 2 electrons.
* 2p orbitals: There are three 2p orbitals (2px, 2py, 2pz), each capable of holding 2 electrons.
3. Filling Orbitals:
* 1s orbital: Fill this orbital with two electrons (represented as ↑↓).
* 2s orbital: Fill this orbital with two electrons (↑↓).
* 2p orbitals: Place one electron in the 2px orbital (↑) and leave the other 2p orbitals empty.
4. Orbital Diagram:
The orbital diagram for boron looks like this:

Key Points:
* Hund's Rule: Electrons will individually occupy each orbital within a subshell before pairing up in the same orbital.
* Pauli Exclusion Principle: Each orbital can hold a maximum of two electrons, and these electrons must have opposite spins.
