Atomic Structure
Atoms consist of three fundamental subatomic particles: protons (positive charge), neutrons (neutral), and electrons (negative charge).
Structure and Bonding
Chemical bonding arises from the electrostatic interactions between valence electrons and atomic nuclei, driving atoms toward stable electronic configurations through ionic, covalent, and metallic bonds.
Chemical Calculations
Chemical calculations apply stoichiometric mole relationships, empirical and molecular formulas, concentration expressions, and limiting reagent analysis to quantitative chemical reactions.
