Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have developed a novel method for investigating the internal structure of atoms and discovered ...

The team uses the "Little Garden" spectrometer to measure spectral lines from reference gas tubes and compares them with ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

THIS little book endeavours to give a comprehen- sive, but not too advanced, treatment of the theory of atomic spectra. The subject is presented so as to avoid the need for much mathematical knowledge ...

Balloons filled with hydrogen and containing metal salts are ignited. When the balloon explodes, the characteristically colored flame for that metal is seen. This is best performed outside or in a ...
