Introduction to Chemistry

smallest particle of an element that has the properties of that element

characteristic of matter that can be observed through a change in the composition of a substance

process in which atoms from one or more substances rearrange, resulting in a different substance or substances

scientific discipline that is concerned with describing matter and how matter behaves

substance in which atoms of two or more elements are bonded together

composed of two atoms

substance composed of atoms that have the same number of protons

characteristic of a substance that depends on the amount of the substance

state of matter that has neither a definite volume nor a definite shape, consisting of particles that are far apart and move randomly to fill their container

combination of two or more substances that are unevenly distributed

combination of two or more substances that are evenly distributed

prediction based on a limited number of observations

characteristic of a substance that is independent of the amount of the substance

statement of what happens under certain conditions that is verified by multiple experiments

state of matter that has a definite volume but not a definite shape, consisting of particles that are close together and flow freely

anything that has mass and occupies space

substance composed of two or more substances that are not chemically bonded

group of atoms that are held together by covalent bonds

existing as a single atom

measurable state or attribute that can be observed without changing the composition of a substance

state of matter consisting of charged particles in a diffuse gaseous state with equal numbers of positive ions and free electrons

observation that does not include measurement or mathematical analysis

observation that includes measurement or mathematical analysis

systematic procedure used by scientists to conduct research consisting of observation, measurement, and experimentation, as well as the formulation, testing, and modification of hypotheses

state of matter that has a definite volume and a definite shape, consisting of particles that are closely packed and move only by vibrating

well-substantiated and experimentally verified explanation that describes phenomena
