|
What are the "main-group elements?"
|
Main-Group Elements: every element but the transition metals.
|
|
|
What is the "Octet Rule?"
|
Octet Rule: Ions accept or donate electrons to conform to the electron configuration of the nearest Noble Gas.
|
|
|
What is "Z(subscript: eff)?"
|
Z(subscript: eff): an element's effective nuclear charge; i.e., the charge an element's outermost electron shell.
|
|
|
How do elements and their ions compare in size?
|
--> Cations are smaller than their neutral atoms because it's lost electrons (has a higher charge as well).
---> Anions are larger than their neutral atoms because of gaining electrons (it's charge is lower as well). |
|
|
What is "ionization energy?"
|
Ionization Energy (E(subscript: i): the amount of energy necessary to remove the highest-energy electron from an isolated neutral atom in the gaseous state.
|
|
|
When moving down a column in the Periodic Table, does the ionization energy needed change, and why?
|
As you go down a column in the Priodic Table, the ionization energy needed decreases.
----> This is because the further away an electron is from the nucleus, the less energy is required to pull away that electron. |
