Periodic Table Of Elements | A table in which all the known elements are arranged by properties and are represented by one or two letters, referred to as chemical symbols. |
Metals | Most elements are metals; they are typically solid, shiny, malleable, and good conductors of heat and electricity. |
Nonmetals | Elements that are typically not shiny, not malleable, and poor conductors of heat and electricity; usually gases or brittle solids. |
Metaloids | Elements that have properties of both metals and nonmetals; sometimes referred to as semiconductors. |
Luster | The way the surface of a mineral reflects light; either metallic or non-metallic such as silky, dull, glassy, or resinous. |
Conductivity The ability of a substance to transfer heat or electrical energy. reaking. . Physical properties Characteristics that can be observed or measured without changing the substance; for example, color, melting point, or | |
Malleability | The ability of something to be reshaped without breaking |
Brittle | A tendency to break rather than flex or bend. |
Insulator | A material that does not conduct heat or electrical current. |
Conductor | A substance that readily transfers heat or electrical energy |
semiconductor A substance that shows the property of electrical conductivity between that of a conductor and that of an insulator; the foundation of modern electronics. | A substance that shows the property of electrical conductivity between that of a conductor and that of an insulator; the foundation of modern electronics. |
Matter Anything that has mass and takes up space. | Anything that has mass and takes up space. |
Classify/Classification | Sort or put into groups based on similar and dissimilar physical, chemical, or biological characteristics. |
Element | A pure substance composed of the same type of atom throughout. |
Physical properties | Characteristics that can be observed or measured without changing the substance; for example, color, melting point |
