he first three ionization energies through of a period element have the following pattern: make a reasonable guess about which element this is. enter its chemical symbol below.

Sagot :

On the basis of the pattern of the ionization energy through a period shown by the element, the element would be aluminium and it has the chemical symbol Al.

Ionization energy is the energy required to extract one electron from the outermost shell of the element.

Electron is extracted from the outermost shell it is called ionization enthalpy 1, when we remove the second electron from the outermost shell it is called ionization enthalpy 2 and so on.

From the given pattern, we can see that the the ionization enthalpy is increasing drastically with every successful elimination of electron.

If the pattern is of the same element, then this element has to be aluminum most probably.

The chemical symbol for aluminum is Al.
