1. Electronic Configuration:
* Thorium's electronic configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p⁶ 7s² 5f¹⁴ 6d²
2. Orbital Notation:
The orbital notation represents the distribution of electrons within each subshell using arrows. Each arrow represents an electron, and arrows pointing in opposite directions represent spins.

Explanation:
* Each orbital (s, p, d, f) can hold a maximum number of electrons:
* s: 2 electrons
* p: 6 electrons
* d: 10 electrons
* f: 14 electrons
* The subshells are filled in order of increasing energy levels.
Important Note: Thorium is a heavy element, and the orbital notation can be more complex due to relativistic effects and exceptions to the Aufbau principle. However, this basic representation provides a good understanding of the electron distribution in its atomic orbitals.
