Here are the essential concepts you must grasp in order to answer the question correctly.
Orbital Diagrams
Orbital diagrams visually represent the distribution of electrons in an atom's orbitals. Each orbital can hold a maximum of two electrons with opposite spins, and the diagram uses arrows to indicate the presence and spin of electrons. Understanding how to construct these diagrams is essential for predicting the electron configuration of elements.

Electron Configuration
Electron configuration describes the arrangement of electrons in an atom's orbitals, following the principles of the Aufbau principle, Pauli exclusion principle, and Hund's rule. For neon (Ne), which has 10 electrons, the electron configuration is 1s² 2s² 2p⁶, indicating that the first two electrons fill the 1s orbital, followed by the 2s and 2p orbitals.

Noble Gases
Noble gases, such as neon, are elements in Group 18 of the periodic table known for their full valence electron shells, making them chemically inert. Neon has a complete outer shell with eight electrons, which contributes to its stability and lack of reactivity. Understanding the properties of noble gases helps in grasping the significance of electron configurations in chemical behavior.
