Matter : Elements , Compounds and Mixtures Classification of Matter 1.Elements 2.Compounds 3.Mixtures Element Definition: Elements – Elements constitute the simplest chemical substances in which all the atoms are exactly the same. Compound Definition: Compounds – Compounds are chemical substances made up of two or more elements that are chemically bound together in a fixed ratio. What is a Compound? When two or more elements chemically combine in a fixed ratio by mass, the obtained product is known as a compound. Compounds can be defined as substances consisting of 2 or more different types of elements in a fixed ratio of its atoms. When the elements combine, some individual property of the elements is lost and the newly formed compound has new properties. Chemical Formula : Compounds are represented by their chemical formula. A chemical formula is a symbolic representation of the proportions of atoms that constitute a particular chemical compound. The chemical formula of wa
Matter : definition and 5 states of matter A glass holds H20 in three states of matter: ice (solid), water (liquid) and vapor (gas). Matter is the "stuff" that makes up the universe — everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Atoms come together to form molecules, which are the building blocks for all types of matter, according to Washington State University. Both atoms and molecules are held together by a form of potential energy called chemical energy. Unlike kinetic energy, which is the energy of an object in motion, potential energy is the energy stored in an object. The Five States Of Matter There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. Solids In a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion,
