An element in the 4th
row of the periodic table has the following ionization energies:
i1 = 762kJ/mol,
i2 = 1021 kJ/mol,
i3 = 1203 kJ/mol,
i4 = 1402 kJ/mol,
i5 = 5002 kJ/mol,
i6 = 8321 kJ/mol,
i7 = 10243 kJ/mol,
i8 = 13210 kJ/mol
What is the identity of the element?
Ge---------> Ge^+ + e^ i1 = 762kJ/mol,
Ge^+ --------> Ge^2+ + e^- i2 = 1021 kJ/mol,
Ge^2+ -----------> Ge^3+ + e^- i3 = 1203 kJ/mol,
Ge^3+ ---------> Ge^4+ + e^- i4 = 1402 kJ/mol, Ge^+ 4 get stabel electronic configuration.
i5 = 5002 kJ/mol,
i6 = 8321 kJ/mol,
i7 = 10243 kJ/mol,
i8 = 13210 kJ/mol
I4 and I5 energy difference is more . so the element is Ge
