WebElements Periodic Table » Calcium » reactions of elements

Calcium is a silvery white metal. The surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium

Flame tests | Causes of Color

The inner core of the candle flame is light blue, with a temperature of around 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red. The further you reach from the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C).

Is Calcium Flammable?

Calcium in its pure form is not particularly flammable. It is a solid metal that melts at about 1548 degrees Fahrenheit (842 degrees Celsius). Some calcium salts and calcium reactions, however, may be more flammable. This fairly common element is not an extreme fire hazard in most situations, however, there are some things you should know.

Flame Photometry (Theory) : Inorganic Chemistry Virtual

Photoelectric flame photometry, a branch of atomic spectroscopy is used for inorganic chemical analysis for determining the concentration of certain metal ions such as sodium, potassium, lithium, calcium, Cesium, etc. In flame photometry the species (metal ions) used in the spectrum are in the form of atoms.

Elimination of phosphate interference in flame photometric

The interference of phosphate in the flame emission of calcium, strontium and barium was studied. The emission intensity decreases proportionally to the amount of interfering anion up to a maximum depression for equimolar amounts of phosphate to metal. A thermostable phosphate is formed before the ion enters the flame.

flame tests - chemguide

Sodium''s familiar bright orange-yellow flame colour results from promoted electrons falling back from the 3p 1 level to their normal 3s 1 level. The exact sizes of the possible jumps in energy terms vary from one metal to another. That means that each different metal will have a different pattern of spectral lines, and so a different flame colour.

Calcium Ca (Element 20) of Periodic Table - Elements

Calcium has a silvery color metal, which is harder than sodium, and softer than aluminium. It is less chemically reactive than the alkaline and other alkaline-earth metals.. It readily forms a white coating of nitride in air, which protects it from further corrosion, and it burns in air with a yellow-red flame.. The metal reacts easily with water and acids and produces hydrogen, which contains
