CHEM 101 Lecture 1: chem chapter 1 notes
Document Summary
Matter is composed of particles: example: atoms, molecules, and subatomic particles such as neutrons, protons, and electrons. How the particles come together dictates the physical properties of matter. Matter is defined as anything that has mass and occupies space (e. g. , has volume). Chemistry is the discipline that seeks to understand matter and its properties. Elements, molecules, and mixtures: the types of matter. Atoms: basic submicroscopic particles that constitute the fundamental building blocks of ordinary matter. Molecules: substances formed when two or more atoms come together (bond) in specific geometric arrangements. Atoms and molecules determine how matter behaves. The state of matter changes from solid to liquid to gas with increasing temperature. its state its physical form (i. e. , solid, liquid, or gas) based on what properties it exhibits; its composition or the types of particles. In solid matter, atoms or molecules pack close to each other in fixed locations.
