Daniell cell
An electrochemical cell in which the anode is the site of Zn metal oxidation, and the cathode is the
site of Cu2+ ion reduction.
Degenerate orbitals
Orbitals that possess equal energy.
Density (ρ)
A physical property of a substance, defined as the mass contained in a unit of volume.
Diamagnetic
A condition that arises when a substance has no unpaired electrons and is slightly repelled by a
magnetic field.
Diffusion
The random motion of gas or solute particles across a concentration gradient, leading to uniform
distribution of the gas or solute throughout the container.
Dipole
In chemistry, a species containing bonds between elements of different electronegativities,
resulting in an unequal distribution of charge in the species.
Dipole-dipole interaction
The attractive force between two dipoles whose magnitude is dependent on both the dipole
moments and the distance between the two species.
