ta atomic number

Element Symbol: Ta; Atomic Number: 73; Classification: Transition metal; Appearance: Shiny blue-gray solid metal Melting point of Tantalum is 2996 °C and its the boiling point is 5425 °C. Tantalum (atomic number 73, symbol Ta) is a hard, heavy metal that is grayish silver in color.The element was discovered by the Swedish chemist Anders Ekeberg in 1802 while Christian Blomstrand proved that niobium and tantalum are different elements in 1864. The unit cell, containing 16 atoms, has a volume of 319.96 cubic Å, according to, List of chemical element name etymologies, List of people whose names are used in chemical element names, List of places used in the names of chemical elements, "Periodic Table – Royal Society of Chemistry", "Atomic weights of the elements 2011 (IUPAC Technical Report)", "Plutonium and its alloys: from atoms to microstructure", https://en.wikipedia.org/w/index.php?title=List_of_chemical_elements&oldid=995837169, Short description is different from Wikidata, Articles with unsourced statements from November 2020, Creative Commons Attribution-ShareAlike License, English word (the symbol Fe is derived from Latin, English word (The symbol is derived from Latin, English word (the symbol Au is derived from Latin, English word (the symbol Pb is derived from Latin, This page was last edited on 23 December 2020, at 04:02. v • d • e. Periodic table. The atomic number can provide insight into the electronic configuration of the element. 1 definition found From WordNet (r) 3.0 (2006) [wn]: Ta n 1: a hard grey lustrous metallic element that is highly resistant to corrosion; occurs in niobite and fergusonite and tantalite [syn: {tantalum}, {Ta}, {atomic number 73}] WordNet ® Princeton University. In 2015 a IUPAC project was started to decide this issue. The element number is its atomic number, which is the number of protons in each of its atoms. Tantalum is a chemical element with atomic number 73 which means there are 73 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. This predicted value is for solid oganesson, not gaseous oganesson. The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given. She has taught science courses at the high school, college, and graduate levels. Word Origin: Greek Tantalos, mythological character, king who was father of Niobe. Tantalum is incorporated into a variety of alloys, conferring high melting point, ductility, strength, and corrosion resistance. Tantalum is practically immune to chemical attack at temperatures lower than 150 °C. Atomic Mass: 180.9479 amu. The corresponding standard atomic weights are: This element sublimes at one atmosphere of pressure. Natural tantalum consists of 2 isotopes: tantalum-180m and tantalum-181. At high temperatures, tantalum has good 'gettering' ability. Natural tantalum has two known isotopes, 180m Ta and 181 Ta. Because of its hardness and corrosion resistance, it is an important refractory metal and is widely used in alloys. What are synonyms for Ta? Calculate the number of protons, neutrons and electrons it contains. Tantalum (Ta) is a gray coloured metal that has the atomic number 73 in the periodic table. The water and the fruit tantalized him, as the water would drain if he bent to drink and the fruit would move away if he reached for it. It is obtained naturally from the mineral columbite-tantalite. Its atomic number is 73 and indicated by the symbol Ta. A chemical element, often simply called an element, is a species of atoms which all have the same number of protons in their atomic nuclei (i.e., the same atomic number, or Z).[1]. After scandium (Sc) and yttrium (Y), it is disputed in the literature as to whether the group continues to lanthanum (La) and actinium (Ac), or to lutetium (Lu) and lawrencium (Lr). Electron Configuration: [Xe] 6s2 4f14 5d3. They are solid (with the exception of mercury, Hg, a liquid). Meaning of ta.
