**"Wavefunction"**() A mathematical function that gives the amplitude of a wave as a function of position (and sometimes, as a function of time and/or electron spin). Wavefunctions are used in chemistry to represent the behavior of electrons bound in atoms or molecules.

a mathematical description of the density in space of the wave associated with a particle, such as an electron in an atom , or with a group of particles, such as all of the easily movable electrons in a copper wire

a mathematical shape centred on the nucleus that defines the shape of the orbitals containing the electrons
