A molecular model system in which a first component representative of an atom includes at least one elongated shank that has a cylindrical section of one cross sectional area with an inwardly extending shoulder and an outwardly extending abuttment located between the shoulder and the part of the component that represents the nucleus. The molecular model system further includes a fastener component that has a hollow tubular portion longitudinally slotted at one end and having an axial length that represents predetermined portion of a covalent radius of the atom. The inner surface at one end of the slotted end portion extends inwardly to be hooked behind the shoulder to interlock with the shank.
