| Question | Answer |
|---|---|
| How many orbitals in a p sublevel? How many p sublevels in the second energy level? | 3 orbitals in a p-sublevel; 1 p sublevel in the second energy level |
| What is the principle that chemical properties of the elements are periodic functions of their atomic numbers? | Periodic law |
| Name FeSO3 | Iron (II) Sulfite |
| Electron configuration for Mn | [Ar] 4s2 3d5 |
| mixture where the components of the moxture are not uniformed | heterogeneous mixture |
| Mixture where the components of the mixture are uniformly distributed | homogeneous mixure |
| when substances are mixed so that they are dispersed on the molecular level | solution |
| the chemical union of 2 or more elements | compound |
| A homogeneous mixture or solid solution of two or more metals | alloy |
| substance that cannot be broken down by chemical means | element |
| two or more substances which have been combined such that each substance retains its own chemical identity | mixture |
| Name HNO3, HBr, HCl | nitric acid, hydrobromic acid, hydrochloric acid |
| How many electrons are in a p sublevel? | 6 electrons |
| In the third energy level? | 8 electrons |
| in an orbital? | 2n^2 electrons |
| In an f sublevel? | 14 electrons |
| In the first energy level? | 2 electrons |
| Compare the ionic/atomic radii of cations/anions | the ionic/atomic radii of a cation is smaller than the atom meaning the anion has a larger ionic/atomic radii |
| Ionic vs covalent compounds? | ionic compounds is usually a reaction b/w a nonmetal and metal and the reaction has to have a net charge of 0; A covalent compound reaction occurs b/w 2 nonmetals and net charge isn't necessary since electrons are shared |
| What is the most reactive halogen and alkali metal? | Fluorine and Francium |
| Is air a compound or a mixture? | mixture |
| Is orange juice a mixture? | yes |
