|---|---|---|---|---|---|
| What are energy levels? | fixed energies an electron can have (s,p,d,f)- different shapes
🗑
|
||||
| What is a quantum? | the amount of energy required to move an electron from one energy level to another energy level
🗑
|
||||
| What is the quantum mechanical model used for? | solving mathematical equations and it determines the allowed energies for an electron and its possible locations
🗑
|
||||
| What is an atomic orbital often thought of as? | a region of space where there is a high probability of finding an electron (hold 2 e-)
🗑
|
||||
| What are the different inadequacies in Rutherford's atomic model? | it couldn't explain the chemical properties of elements
🗑
|
||||
| What did Rutherford's model explain? | what leads to chemical properties of an element, which requires a model that better describes the behavior of electrons- flame test
🗑
|
||||
| What is the Bohr Model (aka "Planetary Model)? | in his model the electrons are only found in specific circular paths, or orbits around the nucleus
🗑
|
||||
| What does each electron have in the Bohr Model? | fixed energy that determine what energy level it is in
🗑
|
||||
| In the Bohr Model, what must the electron do to move to another energy level? | absorb a quantum of energy
🗑
|
||||
| How did Niels Bohr change and improve Ernest Rutherford's Model? | He included newer discoveries about how the energy of an atom changes when it absorbs or emits light. He also considered hydrogen which has one electron.
🗑
|
||||
| What is electron configuration? | the ways that e- are arranged into various orbitals
🗑
|
||||
| What is a spin? | (up arrow or down arrow)
🗑
|
||||
| What are principal energy levels? | (1,2,3, etc.)
🗑
|
||||
| What is the Aufbau Principle? | electrons occupy the orbitals of lowest energy first
🗑
|
||||
| What is the Pauli Exclusion Principle? | each orbital can only hold up to 2 e-; if 2 e- occupy one orbital, they must have opposite spins
🗑
|
||||
| What is the Hund’s Rule? | e- occupy orbitals in a way that makes the # of e- with the same spin direction as large as possible. They fill orbitals singly first, and "single" e-s all have spins in the same direction
🗑
|
||||
| What is ground state? | lowest energy arrangement
🗑
|
||||
| What is excited state? | atom attains a higher energy arrangement
🗑

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.
