Acid pH of less than 7.
Base pH of more than 7.
pH scale used to classify solutions.
Catalyst substance that increases the rate of a chemical reaction.
Chemical change result in the formation of one or more new substances with new chemical and physical properties
Chemical properties be recognized only when substances react or do not react chemically with one another, that is, when they undergo a change in composition.
Compound pure substances that are composed of two or more types of elements that are chemically combined.
Electrons a negatively charged subatomic particle found outside of the nucleus of the atom.
Law of conservation of mass The amount of matter does not change during a chemical reaction, only that the atoms are rearranged to form new substances. This is evidenced in a balanced chemical equation.
Metal elements with similar properties found on the left side of the “staircase” on the periodic table.
Metalloid elements with similar properties that create a “staircase” on the periodic table.
Mixture physical combinations of two or more different substances that retain their own individual properties and are combined physically (mixed together).
Heterogeneous Mixture is not uniform throughout, the component substances can be visibly distinguished.
Homogenous Mixture is uniform throughout, the substances are evenly mixed and cannot be visibly distinguished
Neutrons a subatomic particle with no charge (neutral) found in the nucleus of the atom.
Nonmetal elements with similar properties found on the right side of the “staircase” on the periodic table
Periodic table a quick reference for associating the name and symbol of an element.
Physical change do not change the composition of a substance, only the physical properties
Physical properties can be observed and measured without changing the kind of matter being studied.
Precipitate a solid substance formed when two solutions are chemically combined.
Products new substances formed in a chemical reaction and that they are located on the right side of the arrow in a chemical equation.
Protons a positive subatomic particle found in the nucleus of an atom.
Reactants substances broken apart or combined in a chemical reaction and that they are located on the left side of the arrow in a chemical equation.
