# calcium flame color

Let’s start with the question “Why do atoms emit light?” You probably know that an atom has a nucleus and electrons? ... Barium, Calcium, etc.) Bulk sample emits light primarily due to the motion of the electrons, therefore its spectrum is broad, consisting of a broad range of colors. The flame will color as follows: Barium Chloride: light green; Calcium Chloride: orange red Bookmarks      The color is not as bright yellow as the sodium flame color.

The Romans built vast amphitheaters and aqueducts using calcium oxide cement to bond stones together. When calcium compounds are introduced into a gas flame a red colour is seen; sodium compounds give a yellow flame. When you place a compound in a flame, the flame will change colour depending on the metal ion present in the compound. The usual lab sample is calcium carbonate. We know that Nature loves stability, so the excited atom will lose the energy and fall back to a lower orbital level. This table of flame coloration is modified from the book "Determinative Mineralogy and Blowpipe Analysis" by Brush & Penfield, 1906. If you have more loops, use a different loop for each test. When you heat it, the electrons gain energy and can jump into any of the empty orbitals at higher levels Each of these jumps involves a specific amount of energy being released as light energy, and each corresponds to a particular color. Potassium emmited the most energy because according to the electromagnetic spectrum, dark greens, blues, and purples have a low wavelength, but high energy, and Potassium nitrate burned a pinkish purple color.
