Ionization Energy - Definition, Periodic Table Trends, Factors Affecting

Explain why each successive ionization of an electron requires a greater amount of energy.

Identifying an element from successive ionization energies (worked example)

The successive ionization energies of some element areI1 = 589.5 kJ/mol, I2 = 1145kJ/mol, I3 = 4900 kJ/mol, I4 = 6500kJ/mol, and I5 = 8100 kJ/mol. This pattern ofionization energies suggests that the unknown element is:Select one:a. As b. Kc. Cad. Se. Si
