Bond Length and Bond Energy

Mr. Andersen discusses bond length and bond energy, starting with Kathleen Lonsdale's pioneering work in X-ray crystallography. He explains the forces of attraction and repulsion between atoms, using energy distance graphs to illustrate bond energy and length. The video covers how bond strength is influenced by atomic charges and the number of electrons shared, leading to changes in bond length. The concept of electronegativity and its impact on bond energy is also explored, along with examples of atomic radius affecting bond length. Finally, the video examines how increasing bond numbers, such as moving from single to triple bonds, affects bond energy and length.
