WebThere are over 100 chemical elements. Each element has a unique number of protons in the nuclei of its atoms. This means that the nucleus of each element has a characteristic positive charge. For ... WebThe energy levels of an ionized atom are entirely different from those of the same atom when it is neutral. Each time an electron is removed from the atom, the energy levels of the ion, and thus the wavelengths of the spectral lines it can produce, change. This helps astronomers differentiate the ions of a given element.
