ObjectiveSWBAT write the electron configuration

of elements on the periodic table in longhand and shorthand notation.

Page 5: Bellringer :

Orbital 1: Holds 2 electrons

Orbital 2: Holds 8 electrons

Has 2 sublevels

Page 6: Bellringer :

Each additional orbital has another set of sub-orbitals

Sub

Page 7: Bellringer :

ClarificationQuantum number (n)

Number of arrows!

To find the # of boxes for each sublevel, divide the # of e- by2

Longhand Notation

Write the Longhand

Page 14: Bellringer :

Shorthand (Noble Gas) Notation!

• Almost the same as longhand notation EXCEPT:• Use the last noble gas that is located in the periodic table right before the element.

• Write the symbol of the noble gas in brackets.

• Write the remaining configuration after the brackets.

• Ex: Fluorine: [He] 2s2 2p5
