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 ...

Colors of emission spectra are due to loosely-bound valence electrons being excited in a flame and dropping back down while emitting light. Warning! Once the flame has started, DO NOT add more ...

Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a new approach that combines generative ...

IR spectra reveal the wavelengths absorbed by atomic samples as they interact with infrared light. These spectra can provide ...

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...
