Orbital Blocks on PT
Which color are the Subshells in the s Block?
Red
What is the %probability of NOT finding an Electron inside an Atomic Orbital?
10%
Identify for Beryllium:
1. Period# (P#)
2. Orbital Block (OB)
3. Outermost Subshell (OSS)
1. P# = 2
2. OB = s Block
3. OSS = 2s
What does the Electron Configuration represent?
The Electron Configuration represents the address for Electrons in an Atom.
What can you use the A Group Number to determine?
#Valence Electrons (#Ve-)
Which color are the Subshells in the f Block?
Green
Put these structures in order from largest to smallest: Subshell, Orbital, Principal Energy Shell (PES)
1. PES
2. Subshell
3. Orbital
Identify for Thorium.
1. Period# (P#)
2. Orbital Block (OB)
3. Outermost Subshell (OSS)
1. P# = 7
2. OB = f Block
3. OSS = 7 - 2 = 5f
When writing the Electron Configuration for any Element, what is the first Subshell and #Electrons you ALWAYS write?
1s^2
What can you use the Period# to determine?
#Principal Energy Shells (#PES) the Atom has.
Where is the d Block located on the Periodic Table?
Middle
Where is Principal Energy Shell (PES) 1 located in relation to the Nucleus and how much Energy does it contain?
PES 1 is located closest to the Nucleus and has the lowest Energy.
When writing the Electron Configuration, why is it important to determine the #Electons an Atom has?
It's important to determine the #Electrons an Atom has because that will help you when checking your Electron Configuration at the end. If your Exponents add up to the Atomic Number, you are on the right track!
Write the Noble Gas Configuration (NGC) for Manganese.
[Ar] 4s^2 3d^5
For the Element Sulfur, identify:
A). A Group#
B). Period#
C). #Valence Electrons
D). Metal, Nonmetal, or Metalloid
E). Family Name
A). 6A
B). 3
C). 6
D). Nonmetal
E). Chalcogens
How do you determine the number of a Subshell in the p Block?
#Subshell = Period#
Name the Subshells in Principal Energy Shell (PES) 3.
3s, 3p, 3d
PEP states that each Orbital can contain a maximum of 2 Electrons and each of those Electrons must have an opposite spin.
Write the Electron Configuration (EC) for the Element Tellurium.

D). Metal, Metalloid, or Nonmetal
E). Family Name
A). 7A
B). 4
C). 7
D). Nonmetal
E). Halogens
How do you determine the number of a Subshell in the d Block?
#Subshell in d Block = Period# - 1
How many Orbitals does each f Subshell contain?
7 Orbitals
Explain Hund's Rule (HR).
HR states that when Electrons occupy Subshells containing multiple Orbitals of equal Energy, the Electrons must each be separated into a different Orbital, containing a clockwise spin, before each Orbital receives a second Electron with a counterclockwise spin.
