Elements heavier than iron are made in energy-absorbing processes in large stars, and their abundance in the universe ( and on Earth ) generally decreases with their atomic number.

Elements with atomic numbers 41 through 82 are apparently stable ( except technetium, element 43 and promethium, element 61, which are unstable ) but theoretically unstable, and thus possibly mildly radioactive.

Elements with atomic numbers 83 through 98 are unstable to the point that their radioactive decay can be detected.

Elements with atomic numbers 1 through 40 are all stable, while those with atomic numbers 41 through 82 ( except technetium and promethium ) are metastable.

Elements with atomic numbers 83 through 98 are unstable to the point that their radioactive decay can be detected.

Elements are presented in increasing atomic number.

KREEP, an acronym built from the letters K ( the atomic symbol for potassium ), REE ( Rare Earth Elements ) and P ( for phosphorus ), is a geochemical component of some lunar impact breccia and basaltic rocks.

* Lanthanoid contraction, the decrease in size of the ionic radius of lanthanide elements with their growing atomic number ( series of Rare Earth Elements ( REE ) in the Mendeleev Table )

# Elements which are similar as regards to their chemical properties have atomic weights which are either of nearly the same value ( e. g., Pt, Ir, Os ) or which increase regularly ( e. g., K, Rb, Cs ).

Although best known for its geometric results, the Elements also includes number theory.

Much of the Elements states results of what are now called algebra and number theory, couched in geometrical language.

* Euclid's Elements, the mathematical treatise on geometry and number theory

Euclid devoted part of his Elements to prime numbers and divisibility, topics that belong unambiguously to number theory and are basic thereto ( Books VII to IX of Euclid's Elements ).

Institutionalized forms, however, evolved over time in the shape of a number of different schools, often integrating beliefs and practices that even pre-dated the keystone texts – as, for example, the theories of the School of Naturalists, which synthesized the concepts of yin-yang and the Five Elements.

Elements marking number may appear on nouns and pronouns in dependent-marking languages or on verbs and adjectives in head-marking languages.

Elements of the precautionary approach are reflected in a number of the provisions of the Protocol, such as:

Elements are generated with real number coefficients for a basis.

* 300 Euclid, Greek mathematician, publishes Elements, treating both geometry and number theory ( see also Euclidean algorithm ).

In the Elements, Euclid began with a limited number of assumptions ( 23 definitions, five common notions, and five postulates ) and sought to prove all the other results ( propositions ) in the work.

Elements of the same period have the same number of electron shells ; with each group across a period, the elements have one more proton and electron and become less metallic.

* Euclid's Elements, a 13-book mathematical treatise written by Euclid, that includes both geometry and number theory

Elements of the Choros and Khoits tribes also were present but were too few in number to retain their ulus ( divisions of a tribe ) as independent administrative units.

Elements of a Fock space which are superpositions of states of differing particle number ( and thus not eigenstates of the number operator ) are, therefore, not Fock states.

He wrote also Elements de metaphysique ( 1724 ), a French Grammar on a new plan, and a number of historical essays.

Elements of the first row are limited to a maximum coordination number of 4.

Book IX, Proposition 36 of Elements proves that if the sum of the first terms of this progression is a prime number ( means, a Mersenne prime mentioned above ), then this sum times the th term is a perfect number.

The FX series consisted of a number Computational Elements, or CEs, which included a set of Weitek 1064 / 1065 FPU's and several custom designed support chips to implement a vector processor based upon the popular Motorola 68000 architecture.

Elements used in combination will increase the over-all capability more than the sum of the capabilities of the individual elements.

Elements or particles denser than the fluid move outward under the influence of the centrifugal force.

" In addition to the various works of Brewster already mentioned, the following may be added: Notes and Introduction to Carlyle's translation of Legendre's Elements of Geometry ( 1824 ); Treatise on Optics ( 1831 ); Letters on Natural Magic, addressed to Sir Walter Scott ( 1832 ); The Martyrs of Science, or the Lives of Galileo, Tycho Brahe, and Kepler ( 1841 ); More Worlds than One ( 1854 ).

Proclus introduces Euclid only briefly in his fifth-century Commentary on the Elements, as the author of Elements, that he was mentioned by Archimedes, and that when King Ptolemy asked if there was a shorter path to learning geometry than Euclid's Elements, " Euclid replied there is no royal road to geometry.

Elements with recommended dietary allowance ( RDA ) greater than 200 mg / day are, in alphabetical order ( with informal or folk-medicine perspectives in parentheses ):

But after finding that his book On Writing had more useful and observant things to say about the craft than any book since Strunk and White's The Elements of Style, I have gotten over my own snobbery.

* Elements which are more electropositive than hydrogen such as lithium, sodium, calcium, potassium and caesium displace hydrogen from water, forming hydroxides.

Wotton shares authorship of the quote " Well building hath three conditions: firmness, commodity, and delight ," with Vitruvius, from whose de Architectura Wotton translated the phrase ; some have termed his Elements a paraphrase rather than a true translation, and the quote is often attributed to Vitruvius.

Elements of Titoism are characterized by policies and practices based on the principle that in each country, the means of attaining ultimate communist goals must be dictated by the conditions of that particular country, rather than by a pattern set in another country.

Elements of the Galois group of the rationals, other than the identity and complex conjugation, do not usually act continuously on a complex variety defined over the rationals, so do not act on the singular cohomology groups.

Elements of GF ( p < sup > n </ sup >) may be represented as polynomials of degree strictly less than n over GF ( p ).

Traditional Chinese medicine has more than 4, 000 years of history as a system of medicine that is based on a philosophical concept of balance ( yin and yang, Qi, Blood, Jing, Bodily fluids, the Five Elements, the emotions, and the spirit ) approach to health that is rooted in Taoist philosophy and Chinese culture.

The usage primarily comes to us from translations of Euclid's Elements, in which two line segments a and b are called commensurable precisely if there is some third segment c that can be laid end-to-end a whole number of times to produce a segment congruent to a, and also, with a different whole number, a segment congruent to b. Euclid did not use any concept of real number, but he used a notion of congruence of line segments, and of one such segment being longer or shorter than another.

Adobe has also released a new free image editing web application, Adobe Photoshop Express, with many more limitations than Adobe Photoshop Elements.

She has written or illustrated more than a dozen books, including Unscientific Americans, Parallel Universes, Mondo Boxo, Proof of Life on Earth, The Four Elements and The Party After You Left: Collected Cartoons 1995 – 2003 ( Bloomsbury, 2004 ).

Sir Henry Wotton's 1624 version The Elements of Architecture was more of a free adaptation than a literal translation, while a 1692 translation was much abbreviated.

White ( see The Elements of Style, 1919 ) discourage the English passive, its usefulness is recognized in cases where the theme ( receiver of the action ) is more important than the agent.

In Mandarin, " wǔxíng " is the pronunciation not only of " Five Animals ," but also of " Five Elements ," the core techniques of Xíngyìquán, which also features animal mimicry ( but of 10 or 12 animals rather than 5 ) and, with its high narrow Sāntǐshì ( 三體勢 ) stance, looks nothing so much like a Fujianese Southern style stranded in the North.

An analysis of the isotopes produced, performed at the National Institute of Radioactive Elements in Belgium has shown that the Mo-99 samples produced at ARGUS are characterized by an extreme radiochemical purity, i. e. the impurity content in them is lower than the allowable limits by 2 – 4 orders of magnitude.
