What is the bond dissociation energy or bond energy? | The energy necessary to achieve a separation between atoms |
How is the bond energy defined graphically? | The vertical distance on a graph between the bond length and zero |
How are cation metals named? | Cation name + charge in parenthesis |
How are nonmetal cations named? | Cation name + -ium |
How are monoatomic anion and simple polyatomic anions named (none/one oxygen)? | Given the suffix -ide |
How are simple polyatomic anions with multiple oxygens called? | Suffix -ite or -ate added |
What does adding the prefix hypo- to an polyatomic anion mean? | Relatively less oxygen |
What does adding the prefix per- to an polyatomic anion mean? | Relatively more oxygen |
What is the basis for acid names? | Anions |
If an acid anion ends in -ide what does the acid name start with? | Hydro- |
If an acid anion ends in -ide what does the acid name end with? | -ic |
How do you name a more oxygenated oxyacid? | Add -ic |
How do you name a less oxygenated oxyacid? | Add -ous |
What are the three rules to naming a binary molecular compound? | 1. Name begins with element that is farthest to the left and lowest in the periodic table 2. Add -ide to second element 3. Greek prefix used on first element is necessary |
What is characteristic of crystals? | They have sharp melting points and characteristic shape of well ordered structure |
What is a amorphous solid? | A solid when no characteristic shape and melts over a temperature |
What is the principal quantum number? | This is the first quantum number that designates the shell |
What is the azimuthal quantum number? | This is the second quantum number that designates the subshell (s, p, d and f) |
What is the magnetic quantum number? | This is the third quantum number that designates the orbital of a given subshell (-l to +l) |
What is the electron spin quantum number? | This is the fourth quantum number which can have a value of -1/2 or 1/2 |
What is the Aufbau principle? | This states that with each proton added to create a new element, a new electron is added as well. |
