WebIonisation energy Target level This is a diagnostic probe designed for post-16 students studying chemistry. Topics Ionisation energy, structure of the atom, intra-atomic forces. Rationale This probe is designed to elicit common alternative conceptions about the nature of the interactions between an atomic nucleus and electrons. WebThrough variation of the electron energy in the ion source, near the ionisation potential of the species under study, it is possible to identify radical species in the plasma. This technique has been used to good effect in the identification of radicals such a CF 3 and CF 2 in CF 4 RF plasmas ( Schwarzenbach et al. , 1997 ). devious creatures
