- When light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. This process is also often referred to as photoemission, and the electrons that are ejected from the metal are called photoelectrons.

- 1 A brief note on some of the uses of reactive metals and their compounds relating to this page: 2  Many of the metals give bright flame colours when burnt in air, and the same colours are seen when a compound of the metal is heated strongly in a bunsen flame e.g. calcium/lithium give red, sodium yellow.

Composition Fuel. Charcoal, commonly known in the pyrotechnic industry as black powder is the most common fuel used in fireworks. Normally, all fuels will contain an organic element such as charcoal or thermite. The mechanism by which the fuel functions in the firework is relatively simple.

- Nickel appears to suppress the effect of the carbon burst; however, the nickel spark can be identified by tiny blocks of brilliant white light. Silicon suppresses the carbon burst even more than nickel. When silicon is present, the carrier line usually ends abruptly in a white flash of light.

Titanium Titanium is one of the few elements that burns in pure nitrogen gas, reacting at 800 °C (1,470 °F) to form titanium nitride, which causes embrittlement. Because of its high reactivity toward oxygen, nitrogen and some other gases, titanium filaments are applied in titanium sublimation pumps as scavengers for these gases.

How Do Fireworks Get Their Colors? That means that the different types of metals used in the stars each have a characteristic color. Here are some of the metals and specific compounds that are typically used in fireworks to produce different colors: Red: strontium (strontium carbonate, SrCO3), for intense reds and lithium (lithium carbonate, Li2CO3, or lithium chloride, LiCl) for medium reds. Orange: calcium (calcium chloride, CaCl2)

Why do certain elements change color over a flame? Those colors are as distinctive to each element as fingerprints are to people. As an easy experiment to try at home, put a little table salt in a flame. You will see the same yellow glow as that of a sodium street light, in which the sodium electrons are kicked about by an electric current instead of a flame. Also, a bit of boric acid, which you can get at a pharmacy, will produce a lovely green flame due to the element boron.

Rubidium Facts - Rb or Element 37 Properties: Rubidium may be liquid at room temperature. It ignites spontaneously in air and reacts violently in water, setting fire to the liberated hydrogen. Thus, rubidium must be stored under dry mineral oil, in a vacuum, or in an inert atmosphere. It is a soft, silvery-white metallic element of the alkali group.Rubidium forms amalgams with mercury and alloys with gold, sodium, potassium, and cesium.Rubidium glows red-violet in a flame test. Rubidium can be used to give fireworks a red-violet color. 2  Rubidium is the 23 rd most abundant element in the Earth's crust. 3  Rubidium chloride is used in biochemistry as a biomarker to track where potassium is taken up by living organisms.

A colorless, odorless, nontoxic, nonflammable, liquefied gas Sulfur Hexafluoride is used by the semiconductor industry for plasma etching prior to chemical vapor deposition (CVD). These processes include Oxide etching, Nitride etching, and wafer cleaning. SF 6 gas, which is itself inert, disassociates in the pressence of an RF field to form reactive Fluroide ions.

It's Elemental Red phosphorus is used in safety matches, fireworks, smoke bombs and pesticides. Black phosphorus is also formed by heating white phosphorus, but a mercury catalyst and a seed crystal of black phosphorus are required. Black phosphorus is the least reactive form of phosphorus and has no significant commercial uses.

Phosphorus? White phosphorus is a highly reactive, waxy, white-yellow, transparent solid with acrid fumes. It emits a weak green glow (luminescence) in the presence of oxygen. It is insoluble in water, but soluble in carbon disulfide. White phosphorus ignites spontaneously in air, burning to the pentoxide (P 4 O 10).hosphorus is used in the manufacture of safety matches (red phosphorus), pyrotechnics and incendiary shells. Phosphorus is also used in steel manufacture and in the production of phosphor bronze. Phosphates are ingredients of some detergents.

Q & A: Uses and dangers of radioactive elements Some radioactive elements glow because of their radioactive decays. They emit electrons or alpha particles, changing from one kind of element to another, and as the electrons in the atoms rearrange themselves to the new atom's configuration, they emit light. Radium was used for watch dials because it glows green.horium, a naturally ocurring radioactive element, is used in making mantles for gas and kerosene lamps because thorium oxide glows brightly when heated. The radioactive elements uranium and plutonium are used in the generation of electricity in nuclear power plants.

Why do different elements burn different colors during a flame color? --------------------------------------…. It is based on the observation that light emitted by any element gives a unique spectrum when passed through a spectroscope. When a salt of the metal is introduced into a Bunsen burner flame, the metallic ion produces characteristic color in the flame.he colour you see will be a combination of all these individual colours. The exact sizes of the possible jumps in energy terms vary from one metal ion to another. That means that each different ion will have a different pattern of spectral lines, and so a different flame colour.

Rubidium Rubidium is used as a getter in vacuum tubes because it combines with and removes trace gases. It is also a component in photocells and has been used in making special glasses. Rubidium has been considered for use in ion engines in space shuttles, because it can be easily ionized.Cesium, however, is more efficient.t is a soft, silvery-white metallic element in the alkali group. [See Periodic Table of the Elements ]. Rubidium is the second-most electropositive and alkaline element. As with other alkali metals, it forms amalgams with mercury and alloys with gold, cesium, sodium and potassium.

Europium Element Facts / Chemistry Uses of Europium. Europium oxide (europia) is widely used as a doping agent in phosphors in television sets and computer monitors: valency three europium produces a red radiance and valency two europium produces a blue radiance. When both valencies are combined a white light is produced which is used in compact fluorescent bulbs.

Fireworks One of the most beautiful and entertaining uses of fire occurs in firework displays. Fireworks need a source of combustible material for energy such as black powder, a mixture of charcoal, sulfur, and saltpeter (an old name for potassium nitrate), or smokeless powder such as cellulose nitrate.In addition, fireworks contain substances that give off bright, colorful light when heated.ireworks need a source of combustible material for energy such as black powder, a mixture of charcoal, sulfur, and saltpeter (an old name for potassium nitrate), or smokeless powder such as cellulose nitrate.

74 W Tungsten Description: Named from the Swedish word meaning heavy stone, tungsten is a gray-white metal that is stable and unaffected by air, acids or bases. It has the highest melting point of any element and often is used in alloys that must resist great amounts of heat, such as light-bulb filaments. Tungsten also is used in television tubes, paints, high-temperature lubricants, tanning leather and fluorescent lighting.
