Chemical Bonding and Ionic Bonding Quiz

Study Notes

Chemical Bonding

Chemical bonding is the attraction between atoms that allows the formation of chemical compounds.
The attraction results from electrostatic forces between electrons and nuclei.
Types of chemical bonds include ionic bonds, covalent bonds, and metallic bonds.

Ionic Bonding

Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions.
It occurs when one atom readily loses an electron(s) and another readily gains these electron(s).
The atom that loses electron(s) becomes a positively charged ion (cation), and the atom that gains electron(s) becomes a negatively charged ion (anion).
The electrostatic attraction between the oppositely charged ions forms the ionic bond.
The formation of ions is driven by the atoms' tendency to achieve a stable electron configuration, often a full outermost electron shell.
Ionic compounds typically consist of a metal and a nonmetal.
The attraction between ions are strong, leading to high melting and boiling points in ionic compounds.
Ionic compounds form crystalline structures, often arranged in a regular, repeating pattern.
The arrangement in crystalline structures maximizes the attractive forces while minimizing repulsive forces between ions.
Ionic compounds are generally hard and brittle, and they are often soluble in water.
The electrostatic forces that hold the ions together are relatively strong and are responsible for the high melting and boiling points of ionic compounds.
Examples of ionic compounds include sodium chloride (NaCl), potassium iodide (KI), and magnesium oxide (MgO).

Properties of Ionic Compounds

High melting and boiling points due to strong electrostatic forces between ions.
Brittle nature: disruption of the crystal lattice structure by an applied force leads to repulsion between like charges, resulting in fracture.
Conductivity when molten or dissolved in water: Ions can move freely, carrying charge, when in a liquid or aqueous state.

Formation of Ionic Compounds

Atoms transfer electrons to achieve a stable electron configuration (usually a full outer electron shell).
The loss of electrons by one atom forms a cation, and the gain of electrons by another forms an anion.
The electrostatic attraction between the oppositely charged ions creates an ionic bond.
