Oxidising flame colour
Webcharacteristic colour to an oxidizing flame. This is because the heat from the flame excites the outermost orbital electron to a higher energy level. When the excited electron comes back to the ground state, there is emission of radiation in the visible region as given below: Alkali metals can therefore, be detected by the respective flame ...

When these excited electrons return to the ground state, the absorbed energy is emitted in the visible region of the electromagnetic spectrum and hence the flame β¦
WebThe ionisation energy of alkali metals is very low. The energy of the flame is sufficient to excite the electrons to higher energy level. The excited state is unstable. Hence, the electrons emit energy and come back to the original levels. this emitted energy falls in the visible. the region of the electromagnetic spectrum. this is why alkali ... WebBeryllium and magnesium do not give colour to flame because they (Be and Mg) have a small size and very high ionisation enthalpies. The enthalpy of the flame is not sufficient to excite their electrons to higher energy levels. Other alkaline earth metals impart colour to the flame because they have fairly low ionisation enthalpies, so electrons in their atoms can β¦
