Matter (1. 1)- anything that occupies space and has mass. Mass (1. 1)- a measure of the quantity of matter. Energy (1. 1)- the capacity to move an object or transfer heat. Pure substance (1. 1)- matter that has the same chemical composition, no matter it"s origin. Mixture (1. 1)- a combination of two or more substances that can vary in composition. Element (1. 1)- a substance that cannot be broken down into simpler substances even by a chemical reaction. Metal (1. 1)- an element characterized by luster and the ability to conduct electricity. Nonmetal (1. 1)- an element that typically has a dull appearance and is a poor conductor of electricity.
