Periodic Table
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows (" periods") and columns (" groups"). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order of their atomic numbers an approximate recurrence of their properties is evident. The table is divided into four roughly rectangular areas called blocks. Elements in the same group tend to show similar chemical characteristics. Vertical, horizontal and diagonal trends characterize the periodic table. Metallic character increases going down a group and from right to left across a period. Nonmetallic character increases going from the bottom left of the periodic table to the top right. The first periodic table to become generally accepted was that of the Russian chemist Dmitri Mendeleev in 1869; he formulated the periodic law as ...

29 (Loïc Nottet Song)
"29" is a song by Belgian singer Loïc Nottet, released for digital download on 5 June 2019 by Sony Music as the third single from his second studio album '' Sillygomania''. It was written by Sacha Skarbek and Nottet, while the production was handled by the latter. A piano-driven ballad, the track builds to a "strong and explosive" chorus and features Nottet reaching high notes throughout. The autobiographical lyrics delve on the ending on a relationship and also approach themes of hopelessness, loneliness and struggle. An accompanying music video for the track was uploaded to the singer's YouTube channel on 4 June 2019. Directed by Julien Hosmalin, the critically acclaimed clip depicts Nottet and his love interest, played by Fanny Sage, reaching for each other on top of a levitating Mercedes-Benz car. Commercially, the track charted in the Wallonia and Flanders regions of Belgium. It was also promoted by a live performance for MNM. Background and composition "29" was written b ...

29 (number)
29 (twenty-nine) is the natural number following 28 and preceding 30. It is a prime number. 29 is the number of days February has on a leap year. Mathematics 29 is the tenth prime number. Integer properties 29 is the fifth primorial prime, like its twin prime 31. 29 is the smallest positive whole number that cannot be made from the numbers \, using each digit exactly once and using only addition, subtraction, multiplication, and division. None of the first twenty-nine natural numbers have more than two different prime factors (in other words, this is the longest such consecutive sequence; the first sphenic number or triprime, 30 is the product of the first three primes 2, 3, and 5). 29 is also, * the sum of three consecutive squares, 22 + 32 + 42. * the sixth Sophie Germain prime. * a Lucas prime, a Pell prime, and a tetranacci number. * an Eisenstein prime with no imaginary part and real part of the form 3n − 1. * a Markov number, appearing in the solution ...

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

29 Amphitrite
29 Amphitrite is one of the largest S-type asteroids, approximately in diameter, and probably fifth largest after 15 Eunomia, Eunomia, 3 Juno, Juno, 7 Iris, Iris and 532 Herculina, Herculina. Discovery Amphitrite was discovered by Albert Marth on 1 March 1854, at the private Regent's Park#The villas, South Villa Observatory, in Regent's Park, London. It was Marth's only asteroid discovery. Its name was chosen by George Bishop, the owner of the observatory, who named it after Amphitrite, a sea goddess in Greek mythology. Its historical symbol was a shell and star; it is in the pipeline for Unicode 17.0 as U+1CECF (). Characteristics Amphitrite's orbit is less eccentric and inclined than those of its larger cousins; indeed, it is the most circular of any asteroid discovered up to that point. As a consequence, it never becomes as bright as Iris or 6 Hebe, Hebe, especially as it is much further from the Sun than those asteroids. It can reach magnitudes of around +8.6 at a ...

2029
Predicted and scheduled events * January 1 – Books, films and other works published in 1933 will enter the public domain. * March – The 2029 Special Olympics World Winter Games are scheduled to be held in Switzerland. * April 13 – Asteroid 99942 Apophis, at 335 metres (1,100 feet) wide, will pass Earth less than 32,000 kilometres (20,000 miles) from Earth's surface: closer than geosynchronous satellites. When discovered, it was considered a serious threat to Earth, but since then refined predictions have ruled out any impact risk for the next 100 years. This will be the closest approach of an asteroid this size scientists have predicted. * August 15 – If not triggered earlier, the next United Kingdom general election is scheduled to be held no later than this date. * October 15 – If not triggered earlier, the 46th Canadian federal election is scheduled to be held no later than this date. * October 28 – First round of the 2029 Uruguayan gener ...

AD 29
AD 29 ( XXIX) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Geminus and Geminus (or, less frequently, year 782 ''Ab urbe condita''). The denomination AD 29 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Agrippina the Elder is exiled to the island of Pandataria, and her sons (except Caligula) are imprisoned by Lucius Aelius Sejanus. * Aulus Plautius, later military leader of the invasion of Britain under Emperor Claudius, becomes suffect consul alongside Lucius Nonius Asprenas.

Transition Metal
In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded. The lanthanide and actinide elements (the f-block) are called inner transition metals and are sometimes considered to be transition metals as well. They are lustrous metals with good electrical and thermal conductivity. Most (with the exception of group 11 and group 12) are hard and strong, and have high melting and boiling temperatures. They form compounds in any of two or more different oxidation states and bind to a variety of ligands to form coordination complexes that are often coloured. They form many useful alloys and are often employed as catalysts in elemental form or in compounds such as coordination complexes and oxides. Most are strongly paramagnetic because of their unpaired d electrons, as are many of their compounds. All of the elements that are ...

Twenty-eight (card Game)
Twenty-eight is an Indian trick-taking card game for four players, in which the Jack and the nine are the highest cards in every suit, followed by ace and ten. It thought to be descended from the game 304, along with similar Indian games known as "29", "40" and "56". Overview Twenty-eight originated in India. The game is believed to be related to the European family of Jass card games, which originated in the Netherlands. These games are believed to have been brought to India by Indian South Africans who were also influenced by the Afrikaner game of Klaverjas. Twenty-eight is a very popular game in the state of Bihar. Some believe that the game originated in the Lakhisarai district of Bihar. The game is also very popular in South India, particularly in the state of Kerala where it is known as ''Irupathiyettu'' ( which translates to 'twenty-eight') or ''Thuruppu'' (). Twenty-nine is a variation of the game that is popular in North India and Bangladesh. Both games are also rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
