Lone pairs are pairs of valence electrons that are not involved in chemical bonding and are located on an atom. They play a crucial role in determining the shape, reactivity, and properties of molecules by influencing bond angles and participating in non-covalent interactions.

Valence electrons are the outermost electrons of an atom and play a crucial role in determining its chemical properties and reactivity. They are involved in forming chemical bonds, such as covalent and ionic bonds, and dictate how atoms interact with each other in molecules and compounds.

Chemical bonding is the process by which atoms combine to form molecules and compounds, driven by the attainment of a more stable electronic configuration. The main types of chemical bonds are ionic, covalent, and metallic, each involving different mechanisms of electron sharing or transfer.

Bond angles are the angles formed between three atoms across at least two bonds, reflecting the spatial arrangement of atoms in a molecule. They are crucial for determining the molecular shape and can affect the physical and chemical properties of a substance.

Non-covalent interactions are critical forces that stabilize the three-dimensional structures of biomolecules and mediate interactions between them, without involving the sharing of electron pairs. These interactions, such as hydrogen bonding, ionic interactions, and van der Waals forces, are generally weaker than covalent bonds but are essential for the dynamic and reversible nature of biological processes.
