![]() The periodic table appears by clicking on the inside of the front cover of this text. The significance of the length of the row and the relation among elements in the same row or column will be discussed in Chapter 5. The second list, called the periodic table, arranges the elements in order of increasing atomic number in rows of varying length. This number is as unique to the element as its name or symbol. To know that each element has a number between 1 and 110 called its atomic ![]() Numbers and weights will be discussed in Chapter 4. The list includes the symbol, theĪtomic number, and the atomic weight of the element. While you study chemistry, you will often need a list of the elements. TABLE 3.2 Elements whose name begins with the letter C Symbol The other ten have two-letter symbols (see Table 3.2). One of these, carbon, has a one-letter symbol, C. Eleven elements have names (and symbols) beginning with the letter C. In these two-letter symbols, the first letter is always capitalized and the second is always lowercased. Most other elements have two-letter symbols. TABLE 3.1 Elements with one-letter symbols Symbol Tungsten, discovered in 1783, has the symbol W, for wolframite, the mineral from which tungsten was first isolated. Potassium's symbol, K, comes from kalium, the Latin word for potash. Potassium was discovered in 1807 and named for potash, the substance from which potassium was first isolated. For 12 of these elements, the symbol is the first letter of the name. With the possible exceptions of yttrium (Y) and vanadium (V), you are probably familiar with the names of all elements having one-letter symbols. For 14 of the elements, the symbol consists of one letter. The symbol of an element represents one atom of that element. Seaborg himself was named a Nobel laureate in 1951 in honor of his pioneering work in the preparation of other unknown elements.Įach element has a symbol,one or two letters that represent the element much as your initials represent you. Seaborg was also the first to identify curium at the metallurgical laboratory at the University of Chicago (now Argonne National Laboratory) in 1944. It was first produced in 1950 in the Radiation Laboratory at the University of California, Berkeley, by a team of scientists headed by Glenn Seaborg. Californium is another example of an element named for the place where it was first observed. The small town of Ytterby in Sweden has four elements named for it: terbium, yttrium, erbium, and ytterbium. She was also awarded the Nobel Prize in Chemistry in 1911 for her discovery of the elements polonium (named after Poland) and radium (Latin, radius, "ray"). Marie Curie, a French scientist of Polish birth, was awarded the Nobel Prize in Physics in 1903 for her studies of radioactivity. Curium is named for Marie Curie (1867-1934), a pioneer in the study of radioactivity. Because this element imparts a blue color to a flame, Bunsen named it cesium from the Latin word caesius, meaning "sky blue." Cesium was discovered in 1860 by the German chemist Bunsen (the inventor of the Bunsen burner). The practice of naming an element after one of its properties continues. The Latin name for gold is aurum, meaning "shining dawn." The Latin name for mercury, hydrargyrum, means "liquid silver." Many of these names are already familiar to you - gold, silver, copper, chlorine, platinum, carbon, oxygen, and nitrogen. The world new elements may be announced at any time.Įach element has a name. The search for new elements continues in many laboratories around Time, elements 107 and 109 have been identified among the products of a nuclear By 1980, 106 of these had been unequivocally characterized and acceptedīy the International Union of Pure and Applied Chemistry (IUPAC). ![]() The atoms of each element are chemically distinctĪnd different from those of any other element. Oxygen makes up 46.1% of the mass of Earth’s crust (the relatively thin layer of rock forming Earth’s surface), mostly in combination with other elements, while silicon makes up 28.2%.Elements are pure substances.

The 1934 Nash also used a three-beam system, although in this case with bulbs of the conventional two-filament type, and the intermediate beam combined low beam on the driver's side with high beam on the passenger's side, so as to maximise the view of the roadside while minimizing glare toward oncoming traffic. From highest to lowest, the beams were called "country passing", "country driving" and "city driving". 1933–1934 Packards featured tri-beam headlamps, the bulbs having three filaments. In 1927 the foot-operated dimmer switch or dip switch was introduced and became standard for much of the century. A similar design was introduced in 1925 by Guide Lamp called the "Duplo". The 1924 Bilux bulb was the first modern unit, having the light for both low (dipped) and high (main) beams of a headlamp emitting from a single bulb. The Guide Lamp Company introduced "dipping" (low-beam) headlamps in 1915, but the 1917 Cadillac system allowed the light to be dipped using a lever inside the car rather than requiring the driver to stop and get out. In 1912 Cadillac integrated their vehicle's Delco electrical ignition and lighting system, forming the modern vehicle electrical system. A Birmingham, England firm called Pockley Automobile Electric Lighting Syndicate marketed the world's first electric car-lights as a complete set in 1908, which consisted of headlamps, sidelamps, and tail lights that were powered by an eight-volt battery. Peerless made electric headlamps standard in 1908. Two factors limited the widespread use of electric headlamps: the short life of filaments in the harsh automotive environment, and the difficulty of producing dynamos small enough, yet powerful enough to produce sufficient current. The first electric headlamps were introduced in 1898 on the Columbia Electric Car from the Electric Vehicle Company of Hartford, Connecticut, and were optional. A number of car manufacturers offered Prest-O-Lite calcium carbide acetylene gas generator cylinder with gas feed pipes for lights as standard equipment for 1904 cars. ![]() Thick concave mirrors combined with magnifying lenses projected the acetylene flame light. Acetylene gas lamps were popular in 1900s because the flame is resistant to wind and rain. The earliest headlamps, fuelled by combustible gas such as acetylene gas or oil, operated from the late 1880s. Main articles: Carbide lamp and Gas lighting They can be powered by a battery or a small generator like a bottle or hub dynamo. Bicycle headlamps are often used on bicycles, and are required in some jurisdictions. Other vehicles, such as trains and aircraft, are required to have headlamps. ![]() Headlamp performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities: the US National Highway Traffic Safety Administration states that nearly half of all traffic-related fatalities occur in the dark, despite only 25% of traffic travelling during darkness. Headlamps are also often called headlights, but in the most precise usage, headlamp is the term for the device itself and headlight is the term for the beam of light produced and distributed by the device.
