Metallic Bonding and Reactivity of Metals

Metallic Bonding

Attraction between delocalized electrons and positive ions.

Delocalized Electrons

Electrons that move freely within a metallic lattice.

Positive Ion

Formed when a metal atom loses electrons.

Crystal Lattice

Regular arrangement of positive ions in metals.

Reactivity Series

Ranking of metals based on their reactivity.

Oxidation

Loss of electrons during a chemical reaction.

Reduction

Gain of electrons during a chemical reaction.

Redox Reaction

Simultaneous oxidation and reduction processes.

Metal Oxide

Compound formed when metals react with oxygen.

Malleable

Ability to be hammered into different shapes.

Lustrous

Shiny appearance of metals due to electron movement.

High Density

Metals have a compact arrangement of atoms.

Conductivity

Ability to conduct heat and electricity.

Exothermic Reaction

Reaction that releases heat, e.g., metal with acid.

Electrochemical Series

Ranking of metals based on their electron donation ability.

Electrolysis

Process of using electricity to drive a chemical reaction.

Metal Hydroxide

Compound formed when metals react with water.

Acid-Base Reaction

Reaction between metal and acid producing salt and hydrogen.

Ion-Electron Half Equation

Equation showing oxidation or reduction of a single species.

Chemical Cell

Device converting chemical energy into electrical energy.

Electrolyte

Substance that conducts electricity when dissolved in water.

Spectator Ion

Ion that does not participate in the overall reaction.

Percentage Mass of Copper

(Total mass of metal / GFM of ore) x 100.

Heat Decomposition

Breaking down of compounds using heat, e.g., silver.
