There are three ways to indicate the arrangement of electrons around an atom 1. Orbital Filling Diagram
(gives the most information)
AY
Ex
O2
1s
2s
2p
2. Electron Configuration
(quicker to draw than orbital filling diagrams)
Ex
02
1s 2s 2p
3. Electron Dot shows only the valence (outer energy level) electrons
Ex
Oxygen atom
1. Write orbital filling diagrams, electron configurations, and electron dot diagrams
for the following elements.
