Bonding Flashcards
1
Q
Name the different types of primary bonds
A
- covalent
- ionic
- metallic
2
Q
Name the different types of secondary bonds
A
- London forces (Van der Walls)
- hydrogen
3
Q
Equations to calculate the potential energy U of two atoms
A
U = - A/r^m + B/r^n
r = separation
m = attractive force
n = repulsive force
4
Q
How do you calculate the interatomic forces
A
F = dU/dr
5
Q
calculate the stiffness S of the bond
A
S = d^2U/dr^2
6
Q
calculate the dissociation radius rD, distance required to break the molecule
A
dU/dr = 0
7
Q
calculate the force required to break the molecule
A
F = dU/dr = 0
