Electron Dot Diagrams Quiz

Electron Dot Diagrams

• Electron dot diagrams represent valence electrons as dots around the chemical symbol of an element.
• These diagrams help visualize the number of valence electrons and predict bonding behavior.

Electron Dot Diagram for Lithium

• Lithium (Li) has 1 valence electron, represented as a single dot beside the symbol.

Electron Dot Diagram for Oxygen

• Oxygen (O) possesses 6 valence electrons, illustrated with 6 dots arranged around the symbol.

Electron Dot Diagram for Neon

• Neon (Ne) has a complete octet with 8 valence electrons, depicted as 8 dots evenly spaced around the symbol.

Electron Dot Diagram for Magnesium

• Magnesium (Mg) has 2 valence electrons, illustrated as 2 dots next to the symbol.

Electron Dot Diagram for Iodine

• Iodine (I) contains 7 valence electrons, represented by 7 dots around the symbol.

Electron Dot Diagram for Boron

• Boron (B) has 3 valence electrons, shown as 3 dots near the symbol.

Electron Dot Diagram for Sulfur

• Sulfur (S) has 6 valence electrons, visualized with 6 dots around its symbol.
