Repulsive Interaction Constant Formula:
From: | To: |
Definition: The Repulsive Interaction Constant is the constant scaling the strength of the repulsive interaction between atoms.
Purpose: It helps quantify the short-range repulsive forces that act between atoms when they come very close to each other.
The calculator uses the formula:
Where:
Explanation: The repulsive interaction is scaled by the distance of closest approach raised to the power of the Born exponent.
Details: This constant is crucial in understanding interatomic potentials, material properties, and chemical bonding at short distances.
Tips: Enter the repulsive interaction in Joules, distance in meters, and Born exponent (must be between 5-12). All values must be positive.
Q1: What is the typical range for the Born exponent?
A: The Born exponent typically ranges between 5 and 12, depending on the material and its compressibility.
Q2: How is the distance of closest approach determined?
A: It's the minimum distance to which particles can approach each other, often determined experimentally or through theoretical calculations.
Q3: What units should I use for the repulsive interaction?
A: The repulsive interaction should be entered in Joules (J), the standard SI unit for energy.
Q4: Can this calculator be used for any type of atoms?
A: Yes, as long as you have the appropriate values for the parameters, it can be used for any atomic system.
Q5: Why is the repulsive interaction important?
A: It prevents atoms from collapsing into each other and helps determine equilibrium distances in molecules and solids.
