Periodic Table
Term | Definition |
---|---|
Chemical Property | A characteristic or behavior of a substance that may be observed when it undergoes a chemical change or reaction. |
Flammability | Easily ignited and capable of burning easily. |
Toxicity | The strength of a poison. |
Oxidation | Any chemical reaction that involves the moving of electrons. |
Radioactivity | The emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei. |
Basic/Base | Substances that, in aqueous solution, release hydroxide (OH−) ions, are slippery to the touch, can taste bitter if an alkali, change the color of indicators (e.g., turn red litmus paper blue). |
Acidic | A molecule or ion capable of donating a hydron (proton or hydrogen ion H+). |
Periodic Table | A table of the chemical elements arranged in order of atomic number. |
Periodic Law | A law in chemistry: the elements when arranged in the order of their atomic numbers show a periodic variation of atomic structure and of most of their properties. |
Alkali Metals | Elements that occupy Group IA (1) of the periodic table. They are very reactive. |
Alkaline Earth Metals | Any of the divalent strongly basic metals of group II of the periodic table comprising beryllium, magnesium, calcium, strontium, barium, and radium. |
Halogens | Any of the elements fluorine, chlorine, bromine, iodine, and astatine, occupying group VIIA (17) of the periodic table. They are reactive nonmetallic elements. |
Noble Gases | Any of the gaseous elements helium, neon, argon, krypton, xenon, and radon, occupying Group 18 of the periodic table. |
Transition Metals | Any of the set of metallic elements occupying a central block (Groups IVB–VIII, IB, and IIB, or 4–12) in the periodic table. Chemically they show variable valence and a strong tendency to form coordination compounds. |
Group/Family | A vertical column in the periodic table of elements. |
Period | A horizontal row. All elements in a row have the same number of electron shells. |
