physical property | A physical property is any property that is measurable whose value describes a state of a physical system. |
chemical property | A chemical property is any of a material's properties that becomes evident during a chemical reaction |
reactivity | efers to the chemical reactions of a single substance, the chemical reactions of two or more substances that interact with each other |
flammability, | Flammability is the ability of a substance to burn or ignite, causing fire or combustion. |
metals | a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity |
nonmetals | Seventeen elements are generally classified as nonmetals; most are gases hydrogen, helium, nitrogen, oxygen, fluorine, neon |
metalloids | whose properties are intermediate between those of metals and solid nonmetals. They are electrical semiconductors. |
