Ionic Bonding and Chemical Reactions

Flashcards covering key concepts related to ionic bonding and various types of chemical reactions.

Ion

Atoms that have lost or gained electrons and carry an electrical charge.

Cation

Atoms that have lost electrons to become positively charged ions.

Anion

Atoms that have gained electrons to become negatively charged.

Ionic Compound Formula

Identify the cation and anion, then combine them in a ratio that balances the charges, resulting in a neutral compound.

Synthesis Reaction

When two elements or compounds combine to form a more complex product.

Exothermic

Energy released (in the form of heat, light or electricity).

Endothermic

Energy input (in the form of light, heat or electricity) to break the bonds in the reactants.

Decomposition Reaction

When a compound (only one reactant) breaks down into two simpler substances.

Smelting

Process to obtain a metal from its ore (in a blast furnace).

Single Displacement Reaction

When one element replaces another in a compound.

Double Displacement Reaction

When two reactants exchange a component.

Neutralisation

When an acid reacts with a base to produce salt and water.

Precipitate

An insoluble compound that forms in a precipitation reaction.

Spectator Ions

Ions that do not contribute to the precipitation reaction and are left out of the net ionic equation.

Net Ionic Equation

A representation of a precipitation reaction that includes only the ions directly involved.

Aqueous Solution

A mixture where water is the solvent, and other substances are dissolved in it.
