| Question | Answer |
|---|---|
| Solubility? | amount of a substance that DISSOLVES in a given quantity of solvent at specified conditions of temp. & pressure to produce a saturated solution. |
| Atomic Mass? | the WEIGHTED AVERAGE of the masses of the isotopes of an element. |
| cations? | any atom or group of atoms with a POSITIVE charge. . . They LOSE electrons |
| Anions? | any atom or group of atoms with a NEGATIVE charge. . . They GAIN electrons. |
| Metals? | ~Good conductors of Heat and Electric current~ Tend to be ductile, malleable, and shiny |
| Kinetic Energy? | The energy an object has because of its MOTION. |
| Kinetic Theory of Gasses? | ~ 1. Particles of a gas move independantly of one another. ~ 2. Move rapidly/quickly~ 3. Particles are FAR APART |
| Absolute Zero? | The zero point on the Kelvin temperature scale, equivalent to -273.15 degree C |
| Gasses? | a form of matter that takes the shape and colume of its container,~ has NO definite SHAPE or VOLUME |
| Liquids? | a form of matter that FLOWS,~ has a fixed volume, and an indefinite shape. |
| Solids? | a form of matter that has a definite SHAPE & VOLUME |
| Boiling Point? | the temp. at which the vapor pressure of a liquid is just equal to the external pressure on the liquid. |
| How can you change the boiling point? | ~ change the atmosphere pressure, the lower it is, the less time it takes to boil. |
| Electronegativity? | The ability of an atom to attract electrons when the atom is in a compound. |
| Atomic Size? | INCREASES from top to bottom l l l VDECREASES from left to right. -----> |
| Ionization Energy? | The energy required to remove an electron from an atom in its gaseous state. |
| Metallic Bonds? | ~ bonds between METALS, using free floating valence electrons~ Allows SOLIDS to conduct electricity~ Are/in SOlids |
| Covalent Bonds? | ~ Between NON-METALS~ SHARE electrons~ KNOWN AS MOLECULAR COMPOUNDS!~ They coroporate |
| Ionic Bonds? | ~ Between a METAL &&&& a NON-METAL~ Good Conductor of Electricity |
