Voc on the periodic table
| Question | Answer |
|---|---|
| Dmitri Mendeleev | Russian chemist who worked to come up with the periodic table |
| Lothar Myer | German chemist who came up with a periodic table. |
| Periodic law | The physical and chemical properties of the elements are periodic functions of their atomic numbers. |
| Periodic table | is the arrangement of the elements in order of their atomic numbers so that elements with similar properties fall in the same column or group |
| Noble Gas | Group 18 on the periodic table. Elements in this group are stable because their outer electron shell is full. |
| Lanthanides | are the14 elements with atomic numbers from 58 to 71. cerium to lutetium. Ce to Lu. |
| Actinides | are the 14 elements with atomic numbers from 90 to 103. thorium to lawrencium. Th to Lr. |
| Periodicity | The variation of properties of elements based on their atomic number and position on the periodic table. |
| Period | horizontal row of elements in the periodic table. |
| Family | vertical column of elements in the periodic table |
| Series | a listing of metals according to their decreasing activity |
| Group | horizontal row of elements in the periodic table. |
| s-block elements | are chemically reactive metals. Contains the alkali metals and alkaline-earth metals. Found in column 1 and 2. |
| p-block elements | consist of all elements in group 13 to 18 except helium.Considered with the s block to be the main-group elements. |
| d-block metals | first starts when n equals 3. it is the groups from 3 to 12 which is the transition metals. |
| f-block metals | on the periodic table it is wedge between group 3 and 4. Involve the filling of the 4f sublevel |
| Alkali metals | The elements of group 1 of the periodic table. Have silvery appearance and can be cut by a knife. |
| Alkaline Earth metals | The elements of group 2 of the periodic table. Harder denser and stronger than Alkali metals. |
| metal | an element that is a good conductor of heat and electricity. |
| transition metals | d-block elements, are metals typical metallic properties. Are good conductors and have high luster. |
| main-group or representative elements | an element in the s or p block |
| halogens | elements of group 17.Most reactive nonmetals. |
| atomic radius | one half the distance between nuclei of identical atoms that are bonded together. |
| bonding radius | the distance between two or more elements that are chemically bonded |
| ionization energy | the energy required to remove one electron from a neutral atom of an element |
| electron affinity | The energy that occurs when an electron is added to a neutral atom of an element. |
| valance electron | an electron that is able to be gained,lost, or shared in the formation if a chemical compound. |
| cation | a positive ion |
| anion | a negative ion |
| ion | an atom or group of atoms that have a negative chrage. |
| atomic mass unit | a unit of mass that is exzactly 1/12 the mass of a carbon 12 atom, or 1.660540x10-27 |
| nonmetal | an element that is a poor conductor of electricity and heat. |
| isotope | atoms of the same element that have different masses |
| shielding effect | electrons in the filled sets of s, p orbitals between the nucleus and outer shell electrons somewhat from the effect of protons in the nucleus |
