MBMS Periodic Table
| Term | Definition |
|---|---|
| periodicity | the repetition of similar properties in chemical elements, as indicated by their positioning in the periodic table; the patterns of properties are caused by regular and predictable variations in the atomic structure of the elements |
| Metals | the elements found to the left of the zigzag line in the periodic table; shiny, malleable, ductile, and good conductors of heat and electricity |
| Nonmetals | the elements found to the right of the zigzag line in the periodic table; not malleable nor ductile; poor conductors of heat and electricity; not shiny |
| Metalloids | the elements that border the zigzag line on the periodic table; semiconductors; these have properties of both metals and non-metals |
| Group/Family | a vertical column of elements in the periodic table; these elements share chemical properties |
| Covalent Bond | a chemical bond formed when atoms share one or more pairs of electrons; H2O is an example |
| Period | horizontal row of elements in the periodic table; these elements follow a repeating or periodic pattern as you move from left to right across the row |
| Transition Metals | the elements found in Groups 3-12 on the periodic table; ductile, malleable, and conduct electricity and heat; less reactive than Group 1 or 2 |
| Alkali Metals | the elements in Group 1 of the periodic table; very reactive due to their single outer shell electron; soft, shiny, silver |
| Halogens | the five nonmetallic elements found in Group 17 of the periodic table; F, Cl, Br, I, At; |
| Noble Gas | an element in Group 18 of the periodic table; He, Ne, Ar, Kr, Xe, Rn; these are stable and nonreactive due to a full outer electron shell |
| Lanthanides | the fifteen metallic chemical elements with atomic numbers 57 through 71; found in the top row at the bottom of the periodic table, these are shiny reactive metals |
| Actinides | the 15 metallic chemical elements with atomic numbers from 89 to 103; found in the bottom row under the periodic table, these are all radioactive elements |
| Alkaline-Earth Metals | the elements of Group 2 on the periodic table; less reactive than Group 1 elements |
| Conductor | a material which permits a flow of charged particles as electrical energy or allows the transfer of thermal energy as heat |
| Periodic Table | a tabular arrangement of the elements according to their increasing atomic numbers so that elements with similar properties are in the same column |
| Valence Electron | an electron that is found in the outermost shell of an atom and that determines the atom's chemical properties |
| Energy Level/Electron Shell | an "orbit" followed by electrons around an atom's nucleus; each shell can contain only a maximum number of electrons |
| Ionic Bond | a bond that forms when electrons are transferred from one atom to another resulting in a positive ion and a negative ion; NaCl is an example |
| Metallic Bond | a bond formed by the attraction between positively charged metal ions and the electrons around them; brass and steel are examples |
| Ion | a charged particle that forms when an atom or group of atoms gains or loses one or more electrons |
| Anion | an ion, atom, or molecule which is negatively charged, i.e. has higher number of electrons than protons |
| Cation | an ion, atom, or molecule which is positively charged, i.e. has higher number of protons than electrons |
