Questions
  1. Statement is true
    Yes
    Statement
    Resonance structures share the same skeletal arrangement.
  2. Statement is true
    Yes
    Statement
    The molecule is described by all of them taken together.
  3. Statement is true
    No
    Statement
    The molecule flips between the structures in turn.
  4. Statement is true
    Yes
    Statement
    The contributing forms are called canonical forms.
  5. Statement is true
    Yes
    Statement
    Resonance is needed when one Lewis structure is not enough.
Resonance is a limitation of the notation, not a physical flicker. Source: syllabus Chemistry, Ch 4 Chemical Bonding and Molecular Structure.

Order the steps: draw a Lewis structure

Read exercise and reference answers
Steps
  1. Count the valence electrons of every atom
  2. Arrange the atoms in their skeletal structure
  3. Place one shared pair between each bonded pair of atoms
  4. Distribute the remaining electrons as lone pairs
  5. Add multiple bonds if any atom still lacks a noble gas configuration
Count first, then place, then check. Source: syllabus Chemistry, Ch 4 Chemical Bonding and Molecular Structure.
