Write the following isotope in nuclide notation: tantalum-175. Identify the isotope that has an atomic number of 76 and a mass number of 192. An isotope of an element contains 82 protons and 122 neutrons. What is the symbol for the isotope? Consider the 37Cl isotope. An atom of this is...
The scientific study of matter's characteristics and behaviour is known as chemistry.Chemistry vocabularyandChemistry glossaryare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up ...
tungsten is a metal element with the element symbol W. It has high hardness, high melting point, and is not corroded by air at room temperature; it is mainly used to manufacture filaments, high-speed cutting alloy steels, super-hard molds, and also used in optical instruments and chemical ...
Copper is a chemical element with the symbol Cu (from Latin: cuprum) 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. ...
This electron configuration that does not follow Aufbau principle is not unique to niobium. Discovery Niobium was recognized by British chemist Charles Hatchett (January 2, 1765 to March 10, 1847) in 1801 (Hatchett,1802a-c). Columbium (symbol Cb) was the name originally given by Hatchett...
In the above diagram, the symbol with one curved plate represents a Polarized Capacitor. The curved plate represents the cathode (negative) of the capacitor, and the other plate is anode (positive). Sometimes a plus sign is also added to the positive side. ...
Capacitors are devices which store electrical energy in the form of an electric field. The process is quite similar to the way mechanical springs store energy in the form of elastic material deformation, to the extent that the math describing both is quite similar, save for the variables used....
Mohs hardness is a method of scratching the surface of the tested mineral with a pyramidal diamond needle and measuring the depth of the scratch. the depth of the scratch is the Mohs Hardness Scale, represented by the symbol HM. It is also used to indicate the hardness of other materials....
