The Octet Rule states that atoms tend to gain, lose, or share electrons to achieve a full outer energy level, which typically consists of eight electrons (an octet). This rule helps explain the formation of chemical bonds and the structure of atoms.

Example in atomic structure:

- Neon (Ne) has an atomic number of 10, with an electronic configuration of 1s² 2s² 2p⁶. Its outer energy level is full, with eight electrons, making it a stable atom.
- Sodium (Na) has an atomic number of 11, with an electronic configuration of 1s² 2s² 2p⁶ 3s¹. It has one electron in its outer energy level, which is not a full octet. To achieve an octet, sodium loses one electron to become a positively charged ion (Na+).

Example in electronic configuration:

- Carbon (C) has an atomic number of 6, with an electronic configuration of 1s² 2s² 2p². Its outer energy level has four electrons, which is not a full octet. Carbon can share electrons with other atoms to achieve a full octet, forming chemical bonds.
- Oxygen (O) has an atomic number of 8, with an electronic configuration of 1s² 2s² 2p⁴. Its outer energy level has six electrons, which is not a full octet. Oxygen can share electrons with other atoms or gain electrons to achieve a full octet, forming chemical bonds.

The Octet Rule helps explain how atoms form chemical bonds and achieve stability, which is essential for understanding chemistry and the structure of matter.
