Base dissociation constant (Kb)
The equilibrium constant that measures the degree of dissociation for a base under specific
conditions. For a base BOH:
Basic anhydride
Basic anhydride
An oxide that dissolves in water to form a basic solution.Basic solution
Basic solution
An aqueous solution that contains more OH– ions than H+ ions. The pH of a basic solution is
greater than 7 at 25°C.
Beta (β) particle
Beta (β) particle
An electron produced and ejected from the nucleus during radioactive beta decay.Binding energy
Binding energy
The energy required to break a nucleus apart into its constituent neutrons and protons.Bohr model
Bohr model
The model of the hydrogen atom postulating that atoms are composed of electrons that assume
certain circular orbits about a positive nucleus.
