Chapter 1 Flashcards
Submicroscopic particles that constitute the fundamental building blocks of ordinary matter.
Atom
Two of more atoms that are chemically bonded
Molecule
The science that seeks to understand the behavior of matter by studying the behavior of atoms and molecules.
Chemistry
A tentative interpretation or explanation of the observations.
Hypothesis
Highly controlled procedures designed to generate observations that may confirm or refute a hypothesis.
Experiment
A brief statement of equation that summarizes past observations and predicts future ones.
Scientific Law
A law stating that matter is neither created nor destroyed in a chemical reaction.
Law of conservation of mass
A proposed explanation for observations and laws based on well established and tested hypothesis that presents a model of a way nature works and predicts behavior beyond the observations and laws on which it was based.
Theory
The theory that each element is composed of tiny indestructible particles called atoms, that all atoms of a given element have the same mass and other properties, and that atoms combine in simple, whole-number ratios to form compounds.
Atomic Theory
Anything that occupies space and has mass.
Matter
Mass’ physical form
State
Basic components that make up mass
Composition
Atoms or molecules that are packed close to each other in fixed locations
Solid
Atoms of molecules are in patterns with long range and repeating order.
Crystalline
Atoms or molecules do not have any long range order.
Amorphous
