Atomic orbitals. Computer display of an electronic orbital of the hydrogen atom. The orbital shown here is known as 3d and it is formed by four symmetric lobes,two purple-blue and two red- green,seen sliced in the cartesian plane xy,with the nucleus at the centre of the frame. According to the atomic quantum theory it is not possible to specify a trajectory for the electrons moving around the nucleus. The quantum theory introduces instead the concept of orbitals as regions where there is a given probability of finding the electrons. The coloured bands in the lobes show different probability levels; the probability decreases when moving away from the nucleus | |
