cal- ionisation energy of Li2+
發問:
Li2+ is a lithium atom (Z=3) with only one electron. Obtain the ionisation energy of Li2+. THANKS!!
最佳解答:
The electron of Li2+ ion is at ground state ( 1s ), which is a Hydrogen like atom. you can use Bohr model or QM, E = - Z^2 E_H / n^2 , where E_H is Hydrogen ground state energy = 13.6eV Z= 3, n =1 E = - 9 * 13.6 eV = 122.4eV
