WebLe modèle de Bohr fût parfait pour décrire l'atome d'hydrogène et les autres systèmes à un seul électron (systèmes dits hydrogénoïdes) tels que l'ion hélium \text {He}^+ He+. Malheureusement, il ne s'applique pas au spectre des atomes plus complexes. WebImgur. The energy of the electron of a monoelectronic atom depends only on which shell the electron orbits in. The energy level of the electron of a hydrogen atom is given by the following formula, where n n denotes the principal quantum number: E_n=-\frac {1312} {n^2}\text { kJ/mol}. E n = − n21312 kJ/mol. For a single electron instead of ...
Web18 aug. 2016 · For He+ there are 2 protons in the nucleus ∴ Z = 2 ∴ I.E. = 2.18 ×10−18 ×22 1 = 8.72× 10−18xJ To convert to kJ divide by 1000 ⇒ I.E. = 8.72 × 10−21xkJ This is the energy required to ionise a single He+ ion. To find the energy required to ionise a mole of ions you need to multiply by The Avogadro Constant which is 6.02 × 1023xmol−1.
