The Periodic Table
| Question | Answer |
|---|---|
| metal | a good conductor of heat and electric current |
| halogen | any nonmetal in Group 7A |
| inner transition metal | any element whose highest occupied s sublevel and a nearby f sublevel contain electrons |
| representative element | an element whose highest occupied s or p sublevels are partially filled |
| ionization energy | the energy needed to remove an electron from an atom in the gaseous state |
| alkaline earth metal | an element in Group 2A |
| electronegativity | the tendency of an atom to attract electrons when the atom is in a compound |
| transition metal | an element whose highest occupied s sublevel and a nearby d sublevel contain electrons |
| noble gas | any nonmetal in Group 7A |
| In the periodic table, there is a periodic pattern in the physical and chemical properties of elements when they are arranged in order of | increasing atomic number |
| Which sublevel corresponds to the transition metals in the periodic table | d sublevel |
| The representative elements are | Group A elements |
| The subatomic particle that plays the greatest role in determining the physical and chemical properties of an element is the | electron |
| First ionization energy increases from | left to right across the second period of the periodic table |
| The category of elements that is characterized by the filling of f orbitals is | inner transition metals |
| Electronegativity generally decreases from | top to bottom within a group |
| atomic size generally decreases from | from left to right across a period |
| alkali metals | Elements in Group 1A |
| ion | an atom or group of atoms that has a positive or negative charge |
| cation | ion with a positive charge |
| anion | ion with a negative charge |
| ionization energy | energy required to remove an electron from an atom |
