Open in App. Element : An element is a pure substance that cannot be split into simpler substances and comprises only one type of atom. Example: Hydrogen H 2 , Copper Cu , etc. Compound : A compound is a pure substance in which elements combine chemically in a fixed composition to give a compound. They can be broken down into elements that make up the compound by using chemical or electrochemical methods. The properties of the compound are entirely different from the elements from which it is formed. Example: Water H 2 O , Common salt i. The components of a mixture can be separated by physical methods of separation. Example: A mixture of Sand and Iron Fe can be separated by the use of a magnet physical process where Iron gets attracted to the magnet leaving behind the sand. Seawater is an example of a mixture.

This introduction to chemistry and seawater gives an overview of the concepts and activities explored in this unit and describes how these investigations build an understanding of ocean literacy. Seawater is a mixture made up of water and dissolved substances, including a variety of elements and compounds. With over chemical elements, a system is needed to organize the elements in a way that is meaningful and useful. The properties of elements and compounds are determined by their structures. The internal structure of an atom and the overall structure of a molecule both contribute to how atoms and molecules behave and react.

Matter typically exists in one of three states: solid , liquid , or gas. The state that a given substance exhibits is also a physical property. Some substances exist as gases at room temperature oxygen and carbon dioxide ; others, like water and mercury metal, exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states. Technically speaking, a fourth state of matter called plasma exists—but it does not naturally occur on earth, so we will omit it from our study here.
