If two elements are in the same chemical family then what can be predicted about their spectra

Each of the element will exhibit its own particular spectra.

Explanation:

The spectra differ for every element as the atoms of the elements are distinct. Spectra is because of the discharging of a wavelength when an electron of an atom loses an energy level. Because of the differences in the electrons and the atomic number in various elements, the association between the electrons and nucleus will make the electrons in various elements to change in their state of energy and also their transition to other levels of energy.
