PPT_ 3 Classification of Matter You can enter a subtitle here if you need it  There are only two ways by which matter can be classified. One is to classify it according to its physical state: solid, liquid, or gas. Another is to classify it according to its These are as follows: Mixtures Are classification of matter Mixtures are made up of two or made up of all the same type of more substances which are atom, all the same molecules, mixed together but are not or all the same ionically bonded chemically combined. elements. This means that they can retain Has a constant composition. their original properties. It cant be separated by physical Can be separated by physical means. means.  01 ELEMENTS COMPOUNDS Elements: Simplest kind of matter Cannot be broken down any simpler and still have properties of that element. All one kind of atom. Atoms-are the smallest particle or unit of an element that has the properties of that element. Ex: Hydrogen (H), Oxygen (O), Sulfur (S) Gold (Au), Silver (Ag). Other examples of elements are given in Table 1.2. Differences in the properties of metals, nonmetals and metalloids. Metals Nonmetals Metalloids  Metal s Metals constitute the greatest number of elements in the periodic table. They are located at the left part of, middle part, and the bottom part (the lanthanide and actinide groups) of the periodic table. These elementAs have characteristics that are Propertie Metal s of s Metals are lustrous in nature. (They have a shiny appearance.) Metals are malleable. (because their atoms can move past each other without breaking the mettalic bond, therefore, retaining the structure of metal.) Metals are ductile. Metals are ductile for the same reason that the atoms of metals have the ability to move past each other without breaking the metallic bond. Metals are good conductors of heat and electricity. Metals have free electrons. They conduct electricity well. Propertie Metal s of s Most metals are solid at room temperature except mercury. Francium, cesium, gallium, and rubidium melt at a temperature slightly higher than room temperature. Most metals are hard. Metals tend to be strong because of the metallic bond that keeps the atoms close together. The soft metals, on the other hand, include tin, lead, sodium and copper. Mercury, which is liquid at room temp is also considered as a soft metal. Most metals have high densities. Metals are generally dense since their atoms are closely packed together because of the strong attractive forces. Metals with low densities are sodium, lithium, cesium, and rubidium. Properties of Non- metals Are elements that lack or do not have the characteristics of metals. Non-metals are located at the right most part of the periodic table, except for hydrogen, which is at the leftmost part (the first element of the periodic table).
