The meaning of ATOMIC CLOCK is a precision clock that depends for its operation on an electrical oscillator regulated by the natural vibration frequencies of an atomic system (such as a beam of cesium atoms).
After a brief discussion of the physical significance of the choice of the basis in molecular calculations, the nature and definition of an atomic-orbital basis for use in limited calculations is discussed, in view of the possibility of replacing, say, ordinary 2 s and 2 p Slater orbitals by...
2.41.1 The Molecular Orbital The molecular orbital (MO) is the basic concept in contemporary quantum chemistry.1–3 It is used to describe the electronic structure of molecular systems in almost all models, ranging from simple Hückel theory to the most advanced multiconfigurational treatments. Only...

Therefore, in the atom it is necessary to take into account not only the electrostatic interactions (see above), but also the magnetic interactions, which are determined by the magnetic spin moment and by the orbital magnetic moment connected with the motion of the electron around the nucleus; ...

atomic radius or atomic radii is the total distance from the nucleus of an atom to the outermost orbital of its electron. we define the atomic radius of a chemical element as: the mean or typical distance from the centre of the nucleus to the boundary of the surrounding shells of electrons...
