The successive ionization energies of a certain element are I1= 577.9 kJ/mol, I2 = 1820 kJ/mol, I3= 2750 kJ/mol, I4 = 11,600 kJ/mol, and I5 = 14,800 kJ/mol. This pattern of ionization energies suggests that the unknown element is what element do these ionization energies suggest? Explain your reasoning.

Respuesta :

Answer:

Aluminium

Explanation:

Ionization energy is the amount of energy needed to remove an electron from a gaseous atom to form a gaseous ion.

The difference between the third and fourth ionization energies is great. This indicates a group III element which is in the third period.

This element is Aluminium (Al)
