Chemical Bonding - Ionic vs. Covalent Bonds


Summary

Atoms with eight electrons in their outer shell are stable due to the Octet Rule, which states that atoms share electrons to achieve stability. Carbon atoms can share electrons to complete their outer shell, while hydrogen achieves stability with electrons in its first shell. Sodium loses one electron to reach eight electrons in its outer shell, while chlorine gains an electron to become negatively charged and form ionic bonds. Understanding these principles helps predict how atoms interact and bond in chemical reactions.


Chemically Stable Atoms

Atoms with an outer shell containing eight electrons are considered chemically stable, following the Octet Rule.

Sharing Electrons

Atoms share electrons to assemble an octet in their outer shells to satisfy the octet rule.

Carbon Atom Example

Carbon atoms can share electrons to complete their outer shell, following the Octet Rule.

Carbon Octet Completion

Carbon atoms can form an octet of electrons by sharing with other atoms.

Hydrogen Shell Configuration

Hydrogen atoms have a stable configuration in their first electron shell.

Sodium Electron Configuration

Sodium attains 8 electrons in its outer shell by losing one electron from the third shell.

Chlorine Electron Gain

Chlorine tends to gain an electron, becoming slightly negative and forming ionic bonds with oppositely charged ions.
