About
Topics
- Atomic Interactions
- Interaction Potential
- Van der Waals Force
- Atomic Bonding
Description
Explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction.
Sample Learning Goals
- Explain how attractive and repulsive forces govern the interaction between atoms.
- Describe the effect of potential well depth on atomic interactions.
- Describe the process of bonding between atoms in terms of energy.
