Webr0 = σ* (2^ (1/6)) ≈ 1.122σ Therefore, the equilibrium interatomic spacing is approximately 1.122 times the atomic radius σ. (b) To find the bond energy, we substitute the equilibrium interatomic spacing r0 into the expression for E (r): E_b = 4ε [ (r0/σ)^12 - (r0/σ)^6] E_b = 4ε [ (1.122σ/σ)^12 - (1.122σ/σ)^6] View the full answer Final answer WebThe equilibrium spacing will occur when the bond energy ( Fn) is a minimum. This is when the net forces between the two atoms is zero: Fn=Fa+Fr=0. Fa = attractive force. … red cliffs backpackers
