Electron configurations

Electron Configuration Notes & Practice!

​Learning Intention: We will learn how electrons are shown in their electron configurations and how to apply and adjust for different elements.

GRAB YOUR JOURNAL & CHROMEBOOK!!!!!!!!!
Warm-up: How many electrons will the elements below have?
H=
He=
Li=
Be=
B=

Success Criteria: I will explain to my partner how to find and create the electron configuration of elements.

Agenda:

1. Warm-up

2. Electron Configuration Quizizz

​Word of the day: Octet rule

Lets arrange the desks for the PSAT!

ALL DESKS SHOULD FACE FORWARD!

Title of Lesson: "Electron Configuration Notes"

The Periodic Table is...

• Divided into different sections

• Helps to identify the energy levels of the elements

Electron Configuration

1  s ¹

row #
shell #

possibilities are 1-7

7 rows
subshells

possibilities are

s, p, d, or f
4 subshells

group #

# valence e-

possibilities are:

s: 1 or 2

p: 1-6
d: 1-10
f: 1-14

Total e- should equal

Atomic #

How to Write an Electron Configuration:

1. Start with the shell or period number

2. Followed by the type of orbital (s,p,d and f)

3. Finally the superscript (# that goes above the letter s, p, d or f¹) indicates the number of electrons in the orbital

Example: Be = 1s² 2s²

​I need a reader with a strong set of LUNGS TO READ WHAT IS IN RED!!

Orbitals are s, p, d and f.

**Orbitals d and f are special. Orbital d will begin at 3d not 4d. 4 and 5f orbitals will be separated and added after Lanthium (La) and Actium (Ac) due to spacing and ordering of the Periodic Table.
