For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. greek worth learningWebAug 13, 2024 · Most metals become cations when they make ionic compounds. Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions … greek wraps chapeltown

"WebOct 8, 2013 · The chemicals need to be heated in the flame before emitting colored light because the electrons in each atom need to absorb enough light to cause them to jump from a ground state to an excited state and back to a ground state to emit colored light. Most salts contain a metal and a non-metal. " - How do metal cations become excited

Metals tend to form cations by losing valence electrons. Examine the model of the photoelectric effect. WebJan 25, 2024 · When a particular salt is heated, atoms of an element get excited and the electrons corresponding to that particular element move from their ground state to higher energy levels. As they return to their ground state, they emit photons of very specific energy.

WebWhen a stable atom gains or loses an electron, it becomes an ion. For example, when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they become ions and form NaCl. Sodum is a cation (lost an electron and became positive) and chlorine is an anion (gained an electron and becomes negative) in this situation. WebIn the case of sodium ions (or many other metal ions), the jumps often involve very high energies and these result in lines in the UV part of the spectrum which your eyes can't see. The jumps that you can see in flame tests often come from electrons falling from a higher to a lower level in the metal atoms.

WebIn general, we usually observe only the spectra of the metal, or the cation, in the flame test because most nonmetals tend not to emit in the visible spectrum. The anion may also have low excitation efficiency, so that there are just fewer electrons excited and relaxing and thus less intense light emitted. WebIn this lab, how do the metal cations become "excited"? b. Circle the correct responses to complete the following statement: EM radiation is emitted when electrons make transitions from low / high to low / high energy levels. 2.
