Study Notes
Structural Formulas
- A structural formula shows the arrangement of atoms in a molecule of a compound.
- A Lewis structure shows the valence electrons for each element's symbol.
Condensed Structure
- In a condensed structure, atoms of the same type bonded to one other atom are represented by a subscript.
Perspective Drawing
- A perspective drawing of a compound shows the three-dimensional arrangement of atoms that is not shown in other types of drawings.
Ring Compounds
- When carbon atoms are joined together in rings, cyclic compounds are formed.
Skeletal Structure
- A skeletal structure is also known as a 'stick figure' or 'line angle' structure.
