1:26 PM usatestprep.com ..ooo Sprint Metal Flame Color aum light green calcium brick red copper blue/green lead blue/white potassium 4) A small bit of calcium salt is placed in the bunsen burner flame. As seen in the photograph, the calciumn salt produces a red flame. This characteristic color of calcium tells us all BUT ONE of the following: A) the energy of calcium's electrons is quantifiable. B) calcium's electrons have different energies than other elements. the red color represents the ground state energy of calcium's electrons. since calcium has a discrete wavelength, it's electrons also have discrete C) D) energies. Submit

Explanation / Answer

The characteristic flame of calcium dies not represent the ground state energy of electrons of calcium. The flame colour is obtained as the electrons which get excited to higher energy dudue to heating release energy while returning back to ground state in the form of light energy. The energy difference is the characteristic of an element, therefore the color of flame is different ffor different elements.
