Tantalum is practically immune to chemical attack at temperatures lower than 150 °C. Round to the mass number. Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. Atomic Number: 73. A list of the 118 identified chemical elements, Unless otherwise indicated, elements are primordial – they occur naturally, and not through. Atomic Mass: 180.9479 amu. A popular visualization of all 118 elements is the periodic table of the elements, a convenient tabular arrangement of the elements by their chemical properties that uses abbreviated chemical symbols in place of full element names, but the simpler list format presented here may also be useful. Atomic Number of Tantalum is 73. 2 synonyms for Ta: atomic number 73, tantalum. At higher temperatures, tantalum is more reactive. In 2015 a IUPAC project was started to decide this issue. 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. Tantalum is sometimes, but only rarely, found uncombined in nature. 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]. She has taught science courses at the high school, college, and graduate levels. Tantalum is a blue-gray chemical element and belongs to the group of transition metals. Classified as a transition metal, Tantalum is a solid at room temperature. The element does not have any stable nuclides, and a value in brackets, e.g. The atomic number of tantalum is 73. Tantalum has only two isotopes and one of them, Ta-180, has one of the lowest natural abundances of all naturally occurring isotopes (0.012%). Since 1899 the IUPAC Commission on Isotopic Abundances and Atomic Weights has been evaluating atomic weights and abundances. The melting point of tantalum is 2996 °C; boiling point is 5425 +/- 100 °C; specific gravity is 16.654; valence is usually 5, but may be 2, 3, or 4. Atomic weight of Tantalum is 180.94788 u or g/mol. Chemical symbol for Tantalum is Ta. In the afterlife, Tantalos was punished by being forced to stand in knee-deep water with fruit above his head. Because of its hardness and corrosion resistance, it is an important refractory metal and is widely used in alloys. Ta: Atomic Number: 73: Atomic Mass: 180.9 atomic mass units Number of Protons: 73: Number of Neutrons: 108: Number of Electrons: 73: Melting Point: 2996.0° C: Boiling Point: 5425.0° C: ... (Ta 2 O 5) Tantalum telluride (TaTe 2) Interesting facts: It is highly corrosion-resistant. The corresponding standard atomic weights are: This element sublimes at one atmosphere of pressure. Chemical elements listed by atomic number The elements of the periodic table sorted by atomic number. An atom of iron has 26 protons in its nucleus; therefore the atomic number of iron is 26. Tantalum ek chemical element hae, jiske chemical symbol Ta, atomic number 73 aur atomic mass 180.95 hae. The element number is its atomic number, which is the number of protons in each of its atoms. Atomic Number: 73: Symbol: Ta: Element Category: Transition Metal: Phase at STP: Solid: Atomic Mass [amu] 180.9479: Density at STP: 16.65 g/cm3 Tantalum is a technology-critical element, as it is used in computers, cell phones, and other electronic equipment. Number of protons in Tantalum is 73. Tantalum is immune to body liquids and is a non-irritating metal. The membership of group 3 is contentious. The melting point of tantalum is 3290 degrees Kelvin or 3017.85 degrees Celsius or degrees Celsius. The atomic number of a sodium atom is 11 and its mass number is 23. Tantalum oxide may be used to make a glass with a high index of refraction, with applications including use for camera lenses. The metal's environmental impact is not well-understood.
