what is the rule of delta E= A/r^12 _ B/r^6 ?
Amr Reda said:what is the rule of delta E= A/r^12 _ B/r^6 ?
The "Delta E" in this rule refers to the difference in energy between two particles or atoms. It is a measure of the strength of the interaction between the particles, with a larger Delta E indicating a stronger attraction between them.
The A/r^12 term represents the attractive forces between particles, while the B/r^6 term represents the repulsive forces. As the distance between particles decreases, the attractive forces dominate and the energy decreases, while at very close distances the repulsive forces become dominant and the energy increases.
The exponents 12 and 6 in this rule represent the strength of the attractive and repulsive forces, respectively. The larger the exponent, the stronger the force. This is due to the fact that the potential energy of the interaction between particles decreases exponentially as the distance between them decreases.
No, this rule is specifically applicable to interactions between neutral particles, such as atoms and molecules. It does not apply to interactions involving charged particles, which follow different rules and equations.
In crystallography, this rule is used to calculate the potential energy of interactions between atoms in a crystal lattice. By understanding the strength of these interactions, scientists can better understand the structure and properties of crystals, which is important in fields such as material science and chemistry.
