Ionic Bonding and Chemical Reactions

These flashcards cover key terms and definitions related to Ionic Bonding and Chemical Reactions.

Ionic Bonding

A chemical bond formed by the attraction between a cation and an anion.

Cation

A positively charged ion that is formed when an atom loses electrons.

Anion

A negatively charged ion that is formed when an atom gains electrons.

Polyatomic Ion

A group of atoms that collectively behave as a single charged ion.

Coulomb’s Law

A law stating that the strength of ionic bonds is related to the charge of the ions and the distance between them.

Lattice Structure

A 3D arrangement of oppositely charged ions held together by ionic bonds.

Formula Units

Indicate the ratio of various types of atoms in an ionic compound.

Binary Ionic Compounds

Compounds consisting of two different elements, typically a metal and a nonmetal.

Transition Metals

Metals that do not always have a fixed charge and can form multiple ionic compounds.

Lattice Energy

The energy required to break all ionic bonds in a lattice.

Ion-Dipole Interaction

The interaction between charged ions and the partial charges in polar molecules such as water.

Hydration Sphere

A layer of water molecules that surrounds an ion when an ionic compound is dissolved in water.

Law of Conservation of Mass (CoM)

A principle stating that matter cannot be created or destroyed in a closed system.

Skeletal Equation

An unbalanced chemical equation showing the formulas of reactants and products.

Diatomic Elements

Elements that exist naturally as molecules composed of two atoms of the same element.
