Question | Answer |
Define the Ground State of an element | When all the electrons occupy the lowest available orbital. |
Define Excited State | An unstable condition where electrons have been exposed to stimuli which causes the to absorb energy and move to a higher energy level |
What are some of Dalton's Theories? | 1. Compounds in an element have fixed proportions2. All atoms of a given element are identical3. Atoms are neither created nor destroyed4. Elements are composed of tiny particles known as atoms |
What is an Ionic Compound? | A compound made of a metal and a nonmetal |
What is Pauli's Exclusion Principle? | Electrons in the same orbital must occupy different spins |
What is Hund's Rule? | When illustrating electrons in a compound each box must have at least one electron before moving to the next orbital. |
What are Sigma Bonds? | Single Bonds |
What are Pi Bonds? | An overlapping of electrons after hybridization |
What is the exception to the Octet Rule? | When compounds form coordinate covalent bonds |
For a given amount of gas at a constant temperature...(Boyle's Rule) | Pressure is inversely proportional to volume |
What is Charles' Law? | Volume is directly proportional to temperature at constant pressure. |
At constant volume....(Gaye Lusak's Law) | Pressure is directly proportional to temperature. |
What does evaporation have a cooling effect? | Because the lectrons that leave from the surface have a higher kinetic energy than they should. |
What is Vapor Pressure? | The pressure a gas exerts on upon its own liquid |
When does a liquid boil? | When Vapor Pressure (Vp=1atm) |
What is the equivalent of 1 atm in mmHg? | 760 mmHg |
What is Henry's Law? (Gases) | The amount of gas dissolved is directly proportional to the pressure applied. |
Higher temperatures makes gas... | less soluble |
Higher temperature makes solids | more soluble |
