Bond angle
A bond angle is the angle formed between two bonds that connect to a central atom in a molecule. Imagine the central atom as a hub, and the bonds as spokes radiating from it. For example, in water (H₂O), the bond angle between the two hydrogen atoms is about 104.5 degrees. This angle influences the shape of the molecule and its chemical properties. Bond angles vary based on the arrangement of electrons around the central atom, which is determined by principles of chemistry such as valence shell electron pair repulsion (VSEPR) theory. Understanding bond angles helps explain molecular behavior and reactivity.
