|---|---|---|---|---|---|
| What is Quantum Mechanics? | Theory that explains why the periodic trends in the periodic table exists
🗑
|
||||
| What happens when electrons spin on their axis? | They generate a magnetic
🗑
|
||||
| Electrons spin up and down with the quantum number Ms. What are the values of Ms | +1/2 or -1/2
🗑
|
||||
| What is the maximum number of orbitals in each sublevel? | S - 1 orbital
P - 3 Orbitals
D - 5 Orbitals
F - 7 Orbitals
🗑
|
||||
| Orbitals with the same energy are called? | Degenerate
🗑
|
||||
| A sublevel has less energy when the L value is what? | Lower
🗑
|
||||
| Energy is sublevels fill from what? | Lowest to high
🗑
|
||||
| Pauli exclusion principle | Only 2 electrons per orbital
🗑
|
||||
| What are Anions? | When nonmetal atoms gain enough electrons to have 8 valence electrons
🗑
|
||||
| When are cations formed? | when a metal atom loses all it's valence electrons, resulting in a new lower energy level valence shell
🗑
|
||||
| What is paramagnetism? | Electron configurations with unpaired electrons means that the atom or ion will have a net magnetic field. (They will be attracted to a magnetic field)
🗑
|
||||
| Diamagnetism | All electrons are paired - no magnetic field (slightly repelled by a magnetic field)
🗑
|
||||
| Where is atomic radius greatest? | Bottom left
🗑
|
||||
| The size of an atom is related to what? | The distance of the Valence electrons to the nucleus
🗑
|
||||
| cations are ____ than neutral atoms | Smaller
🗑
|
||||
| Anions are _____ than neutral atoms | Larger
🗑
|
||||
| What is Ionization energy? | minumum amount of energy required to remove electron from atom or ion in Gas state
🗑
|
||||
| When is Ionization energy increased? | Top right of periodic table (opposite of atomic radius)
🗑
|
||||
| Does the electrons get harder to remove the more you remove? | Yes, because there is a greater positive charge, pulling them closer to the nucleus
🗑
|
||||
| What is the highest electron affinity in any period? | Halogen
🗑
|
||||
| When does metallic character increase? | Bottom left
🗑

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.
