|
|
Term
| How do transition metals differ in terms of losing electrons? |
|
Definition
| Transition metals tend to lose electrons from the s subshell first, and then the d subshell because atoms lose electrons from the highest energy shell first |
|

Term
| What do n, l, ml, and ms represent and what values can they take on? |
|
Definition
n = shell; n
l = subshell; from 0 to n-1
ml = orbital; between l and -l
ms = spin; 1/2 or -1/2 |

Term
| What is the Heisenberg Uncertainty Principle? |
|
Definition
| The more we know about the position of a particle, the less we know about its momentum (and vice-versa) |
|
|
Term
| What is the Aufbau Principle? |
|
Definition
| With each new proton added to create a new element, a new electron is added as well |
|
|
Term
|
Definition
| Electrons will not fill any orbital in the same subshell until all orbitals in that subshell contain at least one electron |
