| Question | Answer |
|---|---|
| Who presented a convincing method for accurately measuring the relative masses of atoms. | Stanislao Cannizzaro |
| Who arranged the elements according to their properties along with the atomic mass of the element. | Dmitri Mendeleev |
| Who arranged the periodic table according to the atomic number. | Henry Moseley |
| The physical and chemical properties of the elements are periodic functions of their atomic numbers is what law? | Periodic law |
| An arrangement of the elements in order of their atomic numbers so that elements with similar properties fall in the same column, or group is the? | Periodic table |
| The name of Group 18 | Noble gases |
| The 14 elements with atomic numbers from 58 (Ce) to 71 (Lu) | Lanthanides |
| The 14 elements with atomic numbers from 90 (Th) to 103 (Lr) | Actinides |
| The name of Group 1? | Alkali Metals |
| The name of Group 2? | Alkaline-Earth Metals |
| What are the main-group elements? | The s-block and p-block elements |
| The name of groups 3 - 12? | Transition metals |
| The name of Group 13? | Boron Group |
| The name of Group 14? | Carbon Group |
| The name of Group 15? | Nitrogen Group |
| The name of Group 16? | Chalcogens |
| The name of Group 17? | Halogens |
| 1/2 the distance between the nuclei of identical atoms bonded together. Tells you the volume of the atom. | Atomic Radii |
| What happens to the radii as you go from left to right across the periodic table? | Decreases |
| What happens to the radii as you go down the periodic table? | Increases |
| Why does the atomic radii decrease as you go across the periodic table? | The added electrons in the same energy level are gradually pulled closer to the more positively charged nucleus. |
| Why does the atomic radii increase as you go down a group? | Energy levels are added |
| what is the energy required to REMOVE one electron from a neutral atom of an element? | Ionization energy |
| What happens to the ionization energy as you go from left to right across the periodic table? | Increases |
| What happens to the ionization energy as you go down a group on the periodic table? | Decreases |
| A positive ion | Cation |
| A negative ion | Anion |
| The electrons available to be gained, lost or shared when forming a chemical compound. | Valence electrons |
| Mendeleev noticed that properties of elements usually repeated at regular intervals when the elements were arranged in order of increasing? | atomic mass |
| The discovery of the noble gases changed Mendeleev's periodic table by adding a new? | Group |
| To which group do lithium and potassium belong? | Alkali metals |
| Elements in a group or column in the periodic table can be expected to have similar? | properties |
| Mendeleev predicted that the spaces in his periodic table represented? | undiscovered elements |
| Mendeleev attempted to organize the chemical elements based on their? | properties |
| In the modern periodic table, elements are ordered according to? | increasing atomic number |
| The most useful source of general information about the elements for anyone associated with chemistry is a? | periodic table |
| Argon, krypton and xenon belong to what family? | noble gases |
| The most characteristic property of the noble gases is that they are? | largely unreactive |
| Because the first energy level contains only the 1s sublevel, the number of elements in this period is? | two |
| The elements that border the zigzag line in the periodic table are the? | metalloids |
| The most reactive group of the nonmetals are the? | Halogens |
| How many valence electrons in Group 17? | seven |
