Question

which model uses colored balls and rods to show bonds in a molecule?
dot diagram
ball - and - stick model
space - filling model
structural formula diagram

Explanation:

A ball - and - stick model uses colored balls to represent atoms and rods to represent the chemical bonds between them. Dot diagrams show valence electrons, space - filling models focus on the space occupied by atoms, and structural formula diagrams use lines and symbols to represent bonds and atoms in a 2 - D way.

Answer:

B. ball - and - stick model
