Actinide,  | Any of the elements of the actinide series, which have atomic numbers from 89 (Ac) through 103 (Lr) |
Alkali Metals,  | One of the elements of Group 1 of the periodic table (lithium, sodium, potassium, rubidium, cesium, and francium) |
Alkaline Earth metals,  | One of the elements of Group 2 of the periodic table (beryllium, magnesium, calcium, strontium, barium, and radium) |
| anion | an ion that has a negative charge,  |
| atomic radius | one-half of the distance between the center of identical atoms that are not bonded together,  |
| cation | an ion that has a positive charge,  |
| electronegativity | containing negative electricity; tending to migrate to the positive pole in electrolysis.,  |
| electron affinity | the quantitative measure, usually given in electron-volts, of the tendency of an atom or molecule to capture an electron and to form a negative ion.,  |
| Halogens | One of the elements of Group 17 (fluorine, chlorine, bromine, iodine, and astatine); halogens combine with most metals to form salts,  |
ion,  | one of the electrically charged particles formed in a gas by electric discharge or the like.,  |
| ionization | to separate or change into ions.,  |
| ionization energy | Ionization energy is the energy required to ionize molecules of a substance. When a substance is ionized Positive and Negative ions are formed.,  |
| Lanthanide | A member of the rare-earth series of elements, whose atomic numbers range from 58 (cerium) to 71 (lutetium),  |
| Main group elements | An element in the s-block or p-block of the periodic table,  |
| Periodic law | Periodic law states the physical and chemical properties of the elements are periodic functions of their atomic numbers,  |
| Periodic table | Periodic table is an arrangement of the elements in order of their atomic numbers so that elements with similar properties fall in the same column,  |
| Transition elements | One of the metals that can use the inner shell before using the outer shell to bond,  |
| valence electrons | an electron of an atom, located in the outermost shell (valence shell) of the atom, that can be transferred to or shared with another atom.,  |
