These chemicals are various metal salts that make different, specific colors as they are ... that shows us a pretty colored flame allows astronomers to figure out what distant stars are made of (in ...

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 ...

Salt slurries in petri dishes with methanol are ignited and characteristic colors for various metals are observed. Colors of emission spectra are due to loosely-bound valence electrons being excited ...

Doing so can help scientists understand the basic science of metal-containing compounds and the design of chemical compounds for specific purposes. You can take delight in the amazing colors of ...

It must be noted that clinical laboratories have largely given up flame AAS. However, furnace AAS for heavy metal determinations, particularly in deficiency studies and toxicology, continues to be ...

(Such an abnormal dissociation also obtains in hydrocarbon flame gases 3.) If, as we believe, the dissociation products of metastable carbon dioxide molecules are carbon monoxide and atomic oxygen ...

Rubies and emeralds are great examples of how a small amount of a transition metal—in this case, chromium—can create a ...
