Transcript text: What is referred to as a "group" when discussing molecular shapes?
Solution
Solution Steps
Step 1: Understanding the Concept of a "Group" in Molecular Shapes
In the context of molecular shapes, a "group" refers to any region of electron density around a central atom. This includes both atoms (bonds) and lone pairs of electrons. The arrangement of these groups determines the geometry of the molecule according to the VSEPR (Valence Shell Electron Pair Repulsion) theory.
Step 2: Identifying the Correct Option
Given the options:
Atoms (bonds) and lone pairs of electrons
Atoms (bonds)
Lone pairs of electrons
The correct definition of a "group" in molecular shapes includes both atoms (bonds) and lone pairs of electrons, as both contribute to the electron density around the central atom and influence the molecular geometry.
Final Answer
\(\boxed{\text{atoms (bonds) and lone pairs of electrons}}\)
