Understand the Problem
The question is asking about the concepts of atomic stability, how atoms interact to achieve stability through various types of bonds (ionic, metallic, covalent), and the properties of the compounds formed. It also touches on the structure of molecules, bond polarity, intermolecular forces, and the characteristics of ionic and covalent compounds.
Answer
Atoms become stable by gaining, losing, or sharing electrons to satisfy the octet rule. Cations (positive) and anions (negative) are held by electrostatic forces in ionic bonds. Coordination number and formula units describe ionic crystals. Metallic bonds offer conductivity, while covalent bonds form between nonmetals.
An atom becomes stable by fulfilling the octet rule, which often involves gaining, losing, or sharing electrons to fill its valence shell. In ionic bonds, cations and anions form and are held together by electrostatic forces. Ionic compounds have properties like high melting points. Cations have a positive charge and are formed by metals; anions have a negative charge and are formed by nonmetals. The coordination number is the number of oppositely charged ions surrounding an ion in a crystal. A formula unit is the smallest ratio of ions in an ionic compound. Metallic bonds involve the sharing of free electrons among a lattice of metal atoms, giving metals properties like conductivity and malleability. Covalent bonds form between nonmetals and involve shared electrons, with exceptions like electron-deficient or expanded octet molecules. Bond energy measures the strength of a bond. VSEPR theory helps predict molecular shapes. Bond polarity involves unequal electron sharing, affecting molecular polarity, which differs from intermolecular forces. Ionic compounds are generally stronger and have higher melting points than covalent compounds.

More Information
Atoms strive for stability by achieving a full valence shell configuration, often adhering to the octet rule. Ionic bonds result in structured compounds with distinct properties, while metallic and covalent bonds offer unique electron sharing and conductance characteristics.
Tips
A common mistake is confusing the process of becoming stable with being inert; even stable ions can react under certain conditions. Remember, stability refers to minimal energy configuration.
