If the given sample is in solid state, take a small amount of substance on the tip of platinum wire and heat it directly in the Bunsen burner. If there is no distinct color, then it is ready for use. The loop is then placed in blue part of the gas burner flame. 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. Why does the flame color of calcium is transient? There is an extensive upward motion (on Earth). A flame is a constantly upward "moving" chemical reaction. This is the basis of a flame test. The cations (Cu, Sr, Na, Ba, Ca and Li) absorb energy from the flame.

When flame tested sodium ions range from a yellow to a bright orange flame and potassium ions give a lilac or light purple flame. Because each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce. What color flame is calcium chloride. The usual lab sample is calcium carbonate. Calcium nitrate alone offered no protection at -4 °C. About      Not all metal ions give flame colours. The typical flame temperature is not hot enough to cause atomic excitation and completely break calcium compounds into calcium atoms. The excited electrons are unstable, and they drop back down to the ground state. The salt tested is calcium chloride. When an element is placed in a flame, Energy is absorbed which causes outer electrons to be raised to a higher orbital level. However, the color may be muted, so it can be hard to distinguish between the yellow of sodium or gold of iron. When the electrons are heated, they become excited (energized), and jump to any higher energy level available, such as 7s or 5p. 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.
