Calcium - Wikipedia
Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.Its physical and chemical properties are most similar to its heavier
Why do alkali metals impart characteristic color to their …
Simplistically, when an atom is in the flame, i.e., it receives more energy, an electron in the outer shell of that atom jumps up to a higher shell position. This electron then falls back to is original position and in doing so emits a photon

What are metal salts? What are examples of this? - Quora
In theory, a metal salt is a compound formed when the hydrogen of an acid is replaced by a metal. In practice these substances are often made by reacting metal compounds such as oxides with the acid. Each acid gives its own set of salts: chlorides
Color of Transition Metal Complexes
Color of Transition Metal Complexes The variety of color among transition metal complexes has long fascinated the chemists. For example, aqueous solutions of [Fe(H 2O) 6] 3+ are red, [Co(H 2O) 6] 2+ are pink, [Ni(H 2O) 6] 2+ are green, [Cu(H 2O) 6] 2+ are blue and [Zn(H
Calcium - Periodic table
Calcium was first isolated by Sir Humphry Davy in 1808 in London. In a lecture to the Royal Society in June 1808, Davy described his experiments that year, which produced tiny amounts of metal, at best. He could not find any way to produce more calcium (3)

Essay on Flame test lab report - 980 Words
The Flame Test Lab was an experiment designed to show how elements react when heated. This Lab attempted to prove that when electrons are excited and then calm, they emit a color specific to the element. This test showed that there is a direct coloration between the heat energy being expelled and the movement of electrons from one energy level to the next.
12.4.1 Reactions of calcium and calcium compounds 1. Heat a flake of calcium on wire gauze with a Bunsen burner flame. The calcium burns brilliantly with a red flame and leaves a white residue of calcium oxide. Add drops of water to the calcium oxide in a test

The flame cremation process occurs at 1600-1800 F with the remains in contact with direct flame. Some of the inorganic mineral remains are lost to the air through the stack. The Aquamation process occurs at 200-300°F without any fire at all, and the water circulation in the …
Pyrotechnic Colorant - LiquiSearch
The color-producing species are usually created from other chemicals during the reaction. Metal salts are commonly used; elemental metals are used rarely (e.g. copper for blue flames). The color of the flame is dependent on the metal ion; the anion of the salt has very little direct influence.
