The ratio of the ionization enthalpy of hydrogen and beryllium three positive is |
|
Answer» Answer: Explanation: The energy of a one electron atom or ion in a given quantum state is (to a first approximation) PROPORTIONAL to the SQUARE of the nuclear CHARGE, Z^2. The ionization energy is also proportional to Z^2, since that is the DIFFERENCE between the ground state of the atom/ion and the energy of the separated ion plus electron. The charge of Be^(4+) is four times that of H^+, so the ionization energy of Be^(3+) is 4^2 or 16 times that of H. |
