en CR Chapter 1 Vocabulary 27 Chemical: Any substance that has a definite composition Chemistry: Study of composition, structure, and properties of matter and the changes it undergoes Atom: The smallest unit of an element that maintains the properties of that element Chemical Change: A change in which one or more substances are converted into different substances Chemical Property: The ability of a substance to undergo a change that transforms it into a different substance Chemical Reaction: A reaction in which one or more substances are converted into different substances Compound: A substance that is made from the atoms of two or more elements that are chemically bonded Element: Pure substance made of only one kind of atom Extensive Property: Property that is dependent on how much of a a substance there is Gas: State of matter consisting of particles that have neither a defined shape nor volume Heterogeneous: A mixture where the components are not uniform or have localized regions with differnt properties Homogeneous: Mixture where components are unifrom Intensive Property: Property that does not depend on the amount of the substance Liquid: State of matter that has a definite volume but not shape Mass: Amount of matter in an object Matter: Anything with mass and occupies space Mixture: Two or more substances are combined without chemical bonds Physical Change: Change that can be observed without changing the chemical composition of a substance Plasma: State of matter at extremely high temperatures where all molecules are dissociated and most atoms are ionized Product: Compounds that are formed when a reaction goes to completion Pure Substance: Substance that can be found on the periodic table Reactant: Substances initially present in a chemical reaction that are consumed during to make products Solid: State of matter with a defined shape and volume Solution: Mix of solid and liquid where solid never settles out Group: Vertical column in periodic table Metal: Good conductor of heat and electricity Metalloid: Some characteristics of a metal and some of a non metal Nonmetal: Poor conductor Period: Horizontal column in periodic table
