| Question | Answer |
|---|---|
| Boyles Law | the volume of gas varies inversely with pressure P1V1=P2V2 |
| Charles Law | volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant. V1 V2/T1 T2 |
| Dalton’s Law | total pressure of a mixture of gases is the sum of the partial pressures of all the gases is the sum of the partial pressures of al the gases present PT=P1+P2+P3+… |
| Gay-Lussac’s Law | the pressure and Kelvin temperature of a gas are directly proportional at constant volume P1/T1=P2T2 |
| Atomic Orbitals | a region in space around the nucleus of an atom where there is a high probability of finding an electron |

| The inner transition metals comprise the ___-block | F |
| The transition metals comprise the ___-block (3-12) | D |
| Which element has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 ? | |
| Order of Electron configurations | 1s 2s 2p 3s 3p 4s 3d 4p 4p 3s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p 6f 7d 7f |
| How many electrons does p, d, f, and s hold? | d=10 p=6 f=14 s=2 |
| There are __ periods and __ groups | 7 periods and 18 groups |
| Metals are at the__, non metals__ metalloids | Metals are at the left, non metals at the right and metalloids along the steps |
| The alkali metals belong to | group 1A |
| the alkhali earth metals belong to | group 2A |
| halogens belong to | group 7A |
| rare gas such as neon | group 18 8A |
| transation metals | group 3-12A |
| Valence electron is the same as | their group As |
| Na has __ valence electron | 1 |
| Cations are__ ion | + |
| anions are __ | - |
| metals __ electronis to form __ ions | lose to form positive |
| Non Metals __ electrnos to form __ ions | gain to form negative |
| Metals combine with non metals to form | Ionic bonding |
| Na+F | Na+F- |
| Covalent booding is formed when atoms of _share electrons | non-metals |
| H2 | H-H |
| The name is metallic ions(group 1-3) is the same as the name of the element followed by the word _ or_ example na+ is | Ion or cation sodium ion(cation) |
| The name is non-metallic ions uses the stem of the element's name and ends with__ example Cl- | "ide" chloride |
| fe3+ | Iron(III) ion |
| Cu2+ | Copper(II) |
