Then, What does an orbital diagram look like?

**Orbital diagrams are** pictorial descriptions of the electrons in an atom. Three rules **are** useful in forming **orbital diagrams**. According to the Auf Bau Principle, each electron occupies the lowest energy **orbital**. You jump up a little bit in energy and we get the 2s **orbital** that make it the 2p sublevel.

Considering this, What is Hund rule? **Hund’s Rule**. **Hund’s rule**: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.

**What is the principal quantum number and how is it symbolized?**

**What is responsible for the different size of these orbitals?**

**Size**of

**Orbitals**and Atomic Radii

The increase of **size** in the **orbital** is due to the increase of the quantum number “n”. The more electrons there are, the closer they are to the nucleus due to the stronger interactions between **them**, which decreases the **size** of the **orbital** and the atomic radius.
