Weak acids play a prominent role in organic chemistry. Hydrogen cations (H+1), “protons”, are frequently found in an initial or final step of a sequence of fundamental steps in the
Polyhedral ModelsPolyhedral Models
Introduction to Polyhedral Models An alternative to represent ionic compounds is to use polyhedral models. When we can see the way in which three=dimensional shapes represent the individual
Ionic CrystalsIonic Crystals
Ionic crystals make up a large and important class of substances found in every walk of life that constitute a robust area of cutting edge research
Solid VoidsSolid Voids
To grasp the structure of metals and ionic compounds, you must account for the solid voids. As atoms occupy lattice points, they create a pattern of empty spaces between
How Atoms PackHow Atoms Pack
How atoms pack give rise to their chemical and physical properties. The way atoms stack into three layers produce the three most important unit cells: body-centered cubic, face-centered cubic, and
Ionic CompoundsIonic Compounds
Why Care About Ionic Compounds? The reason ionic compounds are important might not be obvious you. The first time you see them, is usually in general
Bonds From AtomsBonds From Atoms
Bonds form from atoms when electrons feel nearby atoms. Outer electrons rearrange to possess lower energy. This happens three ways. An element is either a metal or nonmetal.
What is Chemistry? Answered!What is Chemistry? Answered!
Every concept in a chemistry textbook solves a problem. Unlike what chemists do in movies, chemists do not just mix things together to see what will happen.
Significant FiguresSignificant Figures
Why Significant Figures Significant figures preserve the precision of measurements. You record data and use numerical values in calculations. Further calculations can only be as accurate as
Autoionization of WaterAutoionization of Water
The autoionization of water describes when water reacts with water in a solution of water. This forms the basis of understanding aqueous acid base chemistry. Do not suspect
