Cesium. For non-transition elements such as rubidium, cesium, and strontium, the most chemically similar element to any other element is always one in the same column of the Periodic Table but in an adjacent row. Since strontium is not in the same column as rubidium but cesium is in the same column and an adjacent row, the answer follows. (This rule is sometimes true also for transition elements, but not always: For example, for elements in columns 8, 9, and 10, the most nearly chemically similar element is one in the same row and an adjacent column within this group, rather than one in the same column but an adjacent row.)

What is the shortest measurement of time?
The smallest unit of time that has been directly measured is about 10-18 seconds. Planck time (about 5.4 x 10-44 seconds) may be the shortest possible length of time, in principle as well as in terms of limit of measurement. It is not yet clear whether or not time is a 'quantized' concept. Not everyone agrees on what time is. Time, however, is clearly a quantized concept. But it is sensitive to frames of reference. Consider that the GPS birds in orbit that tell us where we are via our clever gadgets are moving at orbital velocity. And their "high speed" frame of reference (compared to earth) makes "time" different for them compared to us. This must be accounted for in calculations to achieve accuracy in the computation of a location. With the idea of relativity (which is what it's all about) kept clearly in mind, we can measure the velocity of all kinds of stuff. And do it well. But how small an interval? We can conceptualize infinitely small periods. But the shortest amount of time that we can measure is something on the order of 10 -15 seconds or so. The cesium fountain clock is the ticket to timing something that brief, but the few that exist are used as time standards and not for "timing events" or the like. Wikipedia has knowledge for free, and a nice article on atomic clocks can be found there. A link is provided.
List of Indian scientists And their achievement?
Albert Einstein (1879 - 1955)He is arguably at the pinnacle, if the popularity of all the scientists is taken into account. He demonstrated solutions to a trio of mind-boggling topics in Physics in 1905 and shot into the limelight. Sir Isaac Newton (1642 - 1727)"Philosophiae naturalis principia mathematica" called "Principia" is acknowledged as the greatest scientific book ever published. Sir Isaac Newton wrote this in 1687. Galileo Galilei (1564 - 1642)He was the first to use the telescope for furnishing evidence that the Earth revolves around the Sun. This postulate was in contrast to that held by the majority. Charles Darwin (1564 - 1642)"On the origin of species by means of natural selection" is Darwin's famous book published in 1859. Johannes Kepler (1571 - 1630)Kepler compiled the Mars data which enabled him to propose the "Three Laws of Planetary Motion". Louis Pasteur (1822 - 1895)Some of his works are: separation of mirror image molecules and effect of polarized light, and identification of the parasite that was killing silkworms. James Maxwell (1831 - 1879)He is known for the "Treatise on Electricity and Magnetism" published in 1873. Maxwell independently developed the "Maxwell-Boltzmann kinetic theory of gases". Edwin Hubble (1889 - 1953)"Hubble's Law" stated that galaxies move away from each other at a speed determined by the distance that separated them. He classified galaxies as per their distance, shape, brightness patterns and content. Emil Fisher (1852 - 1919)Some of his works are: synthesis of glucose, fructose, mannose starting with glycerol, and establishing structures for the 16 stereoisomers of the aldohexoses with glucose as the most prominent member. Paul Dirac (1902 - 1984)He received a Nobel prize in 1933 for the work on anti-particles. The "Dirac equation" was a version of the Schrodinger's equation. Archimedes (287 - 212 BC)His major achievements are "The Archimedes principle in hydrostatics", the Archimedes screw and the relation between the surface and volume of a sphere and the circumscribing cylinder. Marie Curie (1867 - 1934)She won the 1903 Nobel prize in Physics and the 1911 Nobel prize in Chemistry. Thomas Alva Edison (1847 - 1931)He set up the first industrial research laboratory in the world and was a world record holder of 1093 patents. Max Planck (1858 - 1947)He introduced the quantum and became the recipient of the Nobel prize for Physics in 1918. Nikola Tesla (1856 - 1943)In 1882, he stated the rotating magnetic field principle and invented the alternating current long-distance electrical transmission system six years later. Aristotle (384 - 322 BC)His works include Physics, Metaphysics, Politics, Poetics, Nicomachean Ethics and De Anima. Leonardo da Vinci (1452 - 1519)He designed bridges, war machines, buildings, canals and forts. Niels Bohr (1885 - 1962)In 1922, he won the Nobel prize for Physics. He developed the "Bohr theory of the atom and liquid model of the atomic nucleus". Nicholas Copernicus (1473 - 1543)He theorized that the Sun was the fixed point around which the motions of the planets takes place. The Earth rotates around its axis once in a day and slow alterations in the direction of this axis cause the precession of the equinoxes. Rene Descartes (1596 - 1650)He wrote "Meditationes de prima philosophia, in quibus Dei existentia and animae a corpore distinctio, demonstratur" in 1641. Wilhelm Conrad Rontgen (1845 - 1923)In 1901, he won the Nobel prize for Physics as he discovered X-rays. Carl Sagan (1934 - 1996)He promoted the Search for Extra Terrestrial Intelligence and was a pioneer of exobiology. Jonas Salk (1914 - 1995)He developed a vaccine for polio in 1952. Alexander Graham Bell (1847 - 1922)He is the inventor of the telephone and the metal detector. Chandrasekhara Venkata Raman (1888 - 1970)He developed the Raman spectroscopy that provides information regarding the molecular structure. Ernest Rutherford (1871 - 1937)He developed atomic theory in 1911 and classified forms of radiation. Joseph John Thomson (1856 - 1940)He received the Nobel prize for Physics in 1907 and developed the mass spectrograph. William Ramsay (1852 - 1916)He independently discovered Helium and shared the discovery or Argon, Krypton and Xenon. Alfred Nobel (1833 - 1896)He was a chemist, engineer, innovator, and armaments manufacturer. He is also the inventor of dynamite. He established a fund for the yearly Nobel prize in the areas of chemistry, physics, literature, international peace and medicine. William Thompson (1775 - 1833)He derived the second law of thermodynamics and proposed the Kelvin temperature scale. James Prescott Joule (1818 - 1889)One determines the rate at which heat is produced by an electric current by using Joule's law. Julius Robert von Mayer (1814 - 1878)Along with James Joule, he discovered the first law of thermodynamics. Henry Bessemer (1813 - 1898)He invented an economical steel-making procedure that burnt off impurities. Robert Bunsen (1811 - 1899)He developed the spectroscope and discovered Cesium and Rubidium. Thomas Graham (1805 - 1869)He developed a technique to separate crystalloids from colloids, which is called "dialysis". Michael Faraday (1791 - 1867)He stated the laws of electrolysis in 1833. Johann Wolfgang Dobereiner (1780 - 1849)He determined the relation between elements and their atomic weight. Amedeo Avogadro (1776 - 1856)He concluded that equal volumes of gases at similar conditions of temperature and pressure have the same number of molecules. William Henry (1773 - 1841)Henry's Law states that the amount of gas absorbed by water increases as the gas pressure rises. John Dalton (1766 - 1844)He developed the atomic theory. Alessandro Volta (1745 - 1827)He invented the practical battery using cells of two types of metals. Antoine Lavoisier (1743 - 1794)He recognized and named oxygen and disproved the phlogiston theory. Charles Augustin de Coulomb (1736 - 1806)He discovered the law of force between two charged bodies. Henry Cavendish (1731 - 1810)He discovered hydrogen and nitric acid. Thomas Newcomen (1663 - 1729)He invented the steam engine. It was eventually replaced by James Watt's improved design. Robert Boyle (1627 - 1691)The Boyle's law describes the inversely proportional relationship between absolute pressure and volume of a gas, that is, if the temperature is constantly maintained in a closed system Blaise Pascal (1623 - 1662)The SI unit of pressure is named after him.
Which element has the same properties as cesium?
Only caesium has the same properties as caesium. There are other elements which have some similar properties.
What is the difference between rubidium and seslium?
If you mean "What is the difference between rubidium and cesium?" then Rubidium and cesium are two different elements.They have similar properties but cesium is denser and has a higher atomic mass.Cesium also reacts more vigorously with water and air.
Is strontium chemically similar with calcium or rubidium?
Cesium. For non-transition elements such as rubidium, cesium, and strontium, the most chemically similar element to any other element is always one in the same column of the Periodic Table but in an adjacent row. Since strontium is not in the same column as rubidium but cesium is in the same column and an adjacent row, the answer follows. (This rule is sometimes true also for transition elements, but not always: For example, for elements in columns 8, 9, and 10, the most nearly chemically similar element is one in the same row and an adjacent column within this group, rather than one in the same column but an adjacent row.)
What are soluble hydroxides?
Lithium, sodium, potassium, rubidium, cesium, calcium, strontium, and barium hydroxides are soluble.
What has similar chemical properties to rubidium?
Rubidium (Rb) can react with many things such as hydrogen because rubidium has one spare electron 2, 8, 18, 8, 1 and hydrogen has only one outer electron so hydrogen in water will reactvigorously with rubidium as hydrogen is desperate to gain one electron and rubidium is desperate to lose one electron and when these bond they form an ion.
What are some reactivity?
lithium, sodium, potassium, rubidium, cesium, francium, beryllium, magnesium, calcium, strontium, barium, radium
What are the members of the alkali family?
Lithium, Sodium, Potassium, Rubidium, Cesium, Francium, Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
What of the following elements would have properties most similar to cesium Cs?
To find elements that are chemically similar, you don't need to look further than the related elements in the same family (columns). The periodic table is formed so elements in the rows have similar chemical properties. Cesium is in the first family, the alkali metals. All metals in this family are similar and will react explosively with water. The reactivity increases as you go down the column, with francium being the most reactive. But since francium is radioactive, I would say rubidium is most similar to cesium.
What elements has properties similar to potassium?
Any element in the alkali metal group would have similar chemical properties, for example they all react easily to water.
What element is found in photocells?
Rubidium and cesium
Which element has the smallest atomic radius rubidium cesium and francium?
Rubidium
What is the name of the compound Cs3PO3?
