Chemistry Term
Metallic Bond
A bond formed by the attraction between positive ions and a shared "sea" of mobile electrons.
Periodic Group
Iron Triad
The group of transition elements containing iron, cobalt, and nickel; known for their magnetic properties.

Electronegativity
The measure of an atom's ability to attract shared electrons in a chemical bond.
Chemistry Term
Allotrope
Different structural forms of the same element (e.g., diamond and graphite are allotropes of carbon).
Periodic Group
Actinides
A group of 15 radioactive elements with atomic numbers 89 to 103; many are synthetic.
Periodic Trend
Ionization Energy
The energy required to remove an electron from an atom in its gaseous state.

Atomic Anatomy
The Nucleus
Contains Protons (positive) and Neutrons (neutral). Most of the atom's mass is here.
Electron Cloud
Electrons orbit in energy levels. Valence Electrons in the outermost shell determine reactivity.
Stability Rule
Octet Rule: Atoms want 8!

The Bond Identity
Ionic: The Thief
Metal + Nonmetal. Electrons are transferred . Forms a crystal lattice.
Covalent: The Partner
Nonmetal + Nonmetal. Electrons are shared . Forms molecules.
Metallic: The Sea
Metal + Metal. Electrons are pooled in a delocalized cloud.
