|
Atomic Orbital
|
A region of high probability of finding an electron
|
|
|
Ground State
|
The lowest energy level
|
|
|
Pauli Exclusion Principle
|
Each orbital has at most two electrons.
|
|
|
Electron Configuration
|
The arrangement of electrons around the atomic nucleus.
|
|
|
Aufbau Principle
|
The tendency of electrons to enter orbitals of lowest energy first.
|
|
|
3p3
What does the first 3 mean? |
First 3 is energy level=period #=quantum number
|
|
|
3p3
What does the p represent? |
p is the sublevel= orbital shape
|
|
|
3p3
What does the last (tiny) 3 represent? |
The number of electrons in that sublevel.
|
|
|
How many orbitals (max) are in these sublevels?
S, P, D, F |
1, 3, 5, 10
|
|
|
How many electrons (max) are in an orbital?
|
2
|
|
|
How many electrons are in these sublevels?
S, P, D, F |
2, 6, 10, 14
|
|
|
How do the electrons "spin" in the orbitals?
|
One is clockwise and one is counter-clockwise.
|
|
|
What do we call the representative elements?
|
The Group A elements.
|
|
|
How is the modern periodic table arranged?
|
By increasing atomic number.
|
|
|
Where are the transition metals?
|
Groups 3-12 or the Group B elements.
|
|
|
Which subatomic particle identifies the atom?
|
The proton
|
|
|
Which subatomic particle describes the properties of an atom?
|
The electron
|
|
|
How does atomic radius change in the periodic table?
|
It increases down a group, and decreases from left to right.
|
|
|
How does Ionization Energy change in the periodic table?
|
It decreases as you go down the periodic table and increases as you go left to right.
|
|
|
How does electronegativity change in the periodic table?
|
Electronegativity is at it's greatest with fluorine and decreases as you go down the periodic table AND top to bottom.
|
|
|
How does Ionic Size change in the periodic table?
|
Ionic size increases as you go down the periodic table and decreases as you go left to right. Cations get smaller left to right, and Anions get smaller left to right.
|
|
|
What is electronegativity?
|
The ability for an atom to attract an electron.
|
|
|
What is ionization energy?
|
The energy required to remove an electron.
|
|
|
What is an ion? And what are the two types?
|
An ion is an atom (or group of atoms) that have gained or lost an electron.
Cations are positive ions. Anions are negative ions. |
|
|
Where is the volume of the atom found?
Where is the density of an atom found? |
The volume of an atom is due to the electrons.
The density of an atom is due to the nucleus. |
