Atomic Structure and Properties

009

Outer Shells of Atoms

• 2 electrons
• 8 electrons
• 8 electrons

Key Definitions

• Isotopes: Atoms of a single element that have a different number of neutrons.
• Valency: The capacity of an atom to give, accept, or share electrons to achieve the octet state.

Ionic Bonding

Formation of Ions

Ions are formed when neutral atoms or molecules gain or lose electrons to achieve a stable, full outer shell. An ion is an atom that has lost or gained an electron.

• If an atom has lost an electron, it becomes a positive ion.
• If an atom has gained an electron, it becomes a negative ion.

Ionic Bonds

An ionic bond is the electrostatic attraction between a positively charged metal ion (cation) and a negatively charged non-metal ion (anion). Opposite... Continue reading "Chemical Bonding: Ionic, Covalent, and Metallic Explained" »

Model Essay (About 350 Words)
