🗑
|
||||
| wave length | a shortest distance between equivalent points on a continuous wave
🗑
|
||||
| frequency | the number of waves that pass a certain point per second
🗑
|
||||
| amplitude | a waves height from the origin to the crest or from the origin to a trough
🗑
|
||||
| electromagnetic spectrum | consist of all forms of the electromagnetic radiation with the only differences being their frequency and waves length
🗑
|
||||
| quantum | the minnimum amount of energy that can gained or lost by an atom
🗑
|
||||
| photoelectric effect | electrons called photoelectrons are emitted from a metal's surface when light of a certain frequency shines on the surface
🗑
|
||||
| photon | a particle of a electromagnetic radiation with no mass that carries a quantum of energy
🗑
|
||||
| atomic emission spectrum | the set of frequencies of the electromagnetic waves emitted by atoms of the elements
🗑
|
||||
| ground state | the lowest allowable energy state of an atom
🗑
|
||||
| de Broglie equation | predicts that all moving particles have wave characteristics
🗑
|

||||
| pauli exclusion principle | states that a maximum of two electrons may occupy a single atomic orbital but only if the electrons have opposite spins
🗑
|
||||
| hund's rule | states that single electrons with the same spin must occupy equal energy orbital before additional electrons with opposite spins can occupy the same orbitals
🗑
|
||||
| valence electrons | electrons in the atom's outermost orbital
🗑
|
||||
| electron-dot structure | consist of the element's symbol which represents the atomic nucleus and inner-level electrons surrounded by dots representing the atom's valence electrons
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
