WebJul 20, 2024 · The periodic table gets its name because of the way the elements are arranged – in rows and columns. The horizontal rows which go from left to right are called ‘periods’ and the vertical columns which go from up to down are called ‘groups’. In the naturally occurring category the element Astatine (At) is the rarest element on Earth. WebIodine with the symbol ‘I’ is a dark grey or purple blackish nonmetallic element with atomic number 53 in the Periodic Table. It is the least reactive and most electropositive halogen, even though it can form compounds with many elements. It is mainly found on Earth as the water-soluble iodide in brine pools and oceans.

WebModern periodic table. In the year 1913, English physicist Henry Moseley studied the wavelength of the characteristic x-rays By using different metals as anti cathode and showed that the square root of the frequency of the line is related to the atomic number. On the basis of the above observations Moseley gave the modern periodic law which states that : WebPeriodic Table of Chemical Elements.

WebAll existing matter in our surroundings is made up of basic units known as elements. Initially, in 1800, only 31 chemical elements were discovered. After some advancement in technology in 1865, about 63 more elements were discovered. This created the need for the periodic classification of elements. Presently, there are 118 elements known to us.

WebWhen an atom loses an electron it forms a cation and when it gains an electron it becomes an anion. The Ionic radius can be described as the distance between the nucleus of an ion and the outermost shell of the ion. The atomic size of a cation will be smaller than that of the parent atom. An anion is relatively larger in size than its parent atom. WebNiobium is a chemical element with atomic number 41 and is represented with the symbol Nb in the Periodic Table. It is a soft, ductile transition metal which is resistant to corrosion due to the presence of an oxide layer on its surface. It is one of the most common elements found in the Earth’s Crust. It is often found in the pyrochlore mineral.
