One of the 3 basics forms of matter, gases are an important part of chemistry.Their physical behavior can be modeled and described mathematically.
The atom is the basic building block of chemistry. Understanding the structure and energetics of the atom is a key to understanding more complicated particles such as molecules.
The forces between molecules will govern their physical properties and are a key component to understanding chemical interactions.
All of our observable science is governed by thermodynamics - which is a study of the energy requirements and demands of matter interaction.
The fundamentals of chemistry consists of nomenclature, stoichiometry, and basic reaction calculations.
