Document Summary

Test:each question is vocabulary, understanding the concepts, and applying the concepts. Fyi: not going to test on it. Anything that takes up space= study of chemistry. Anything that takes up space and has mass= matter. All biological matter is composed of elements--a substance that cannot be broken down to other substances by chemical reactions z. Substance consisting of two or more elements in a fixed ratio= compound. Atoms that make up living things= oxygen, carbon, hydrogen, and nitrogen. Elements required by an organism in relatively minute quantities= trace elements. Every element has its own unique atom. An element"s chemical properties depend on the structure of its atoms--the smallest unit of matter that still retains the properties of an element. Atoms are composed of three types of large subatomic particles. Number of protons= atomic number--above element symbol on periodic table. Nucleus of an atom is made up of protons and neutrons. Electron cloud is where electrons are located.
