Final answer:
In drawing a Lewis structure, having knowledge about the bond energy is not necessary. It is essential only to know the types of atoms in the molecule, the number of valence electrons, and the number of atoms in the molecule.
Step-by-step explanation:
To answer the student's question, when drawing a Lewis structure, it is NOT necessary to know the bond energy (A). What you do need to know includes the type of atoms in the molecule (B), the number of valence electrons (C), and the number of atoms in the molecule (D).
Steps for Writing Lewis Structures
- Arrange the atoms to show specific connections.
- Determine the total number of valence electrons in the molecule or ion.
- Place a bonding pair of electrons between each pair of adjacent atoms to give a single bond.
The Lewis electron structure of a molecule or polyatomic ion includes all bonding electron pairs as lines (bonds) and lone pairs (non-bonding electron pairs) as pairs of dots around each atom without considering bond energy, which is more relevant to bond strength and reaction dynamics rather than the electron structure representation.
