High ionisation energy:
The high ionisation energy of helium (24.6 eV) makes it a potential gas to be used in plasma source.
The nitrogen gas is generally not used as a plasma gas in plasma based atomic emission spectrometry because the excited nitrogen emits a complex band spectrum that can cause undesirable spectral interference.
Polychromator is a type of simultaneous spectrometer. It has a fixed diffraction grating monochromator and multiple 'exit slits' with associated photomultipliers. Every of the photomultiplier is optimized to detect a specified wavelength corresponding to an element of interest. The emission radiation from the source is dispersed by the grating and sent through different exit slits to be detected by appropriate photomultiplier tube.
Explain Lewis base and a nucleophile Species A is a. Carbon B is an electrophile. Carbon C is a leaving group towards carbon B but also a nucleophile towards carbon D. Carbon D
Q. Explain Valence Bond Theory? This concept starts with the assumption that the bond between the metal ion and the ligand is basically covalent in nature. In order to form a c
Application of mesomeric effect
Tert-butylamine Tert-butylamine cannot be prepared by the Gabriel synthesis because it would require that the nitrogen of phthalimide be alkylated with tert-butyl bromide in an
I want to know how to calculate hybridisation of an atom in a given compound like I want to calculate hybridisation of Boron & Oxygen in this boric acid compound H 3 BO 3 I even w
The only nonradioactive isotope of fluorine has 9 protons and 10 neutrons. a. What is its mass number. b. Write the full symbol of this atom.
Coordination complexes are so pervasive that the structure and reactions are defined in many ways, sometimes confusingly. The atom within a ligand that is bonded to the central ato
Q. What happens to the energy values of d- orbitals? Let us see what happens to the energy values of d- orbitals under these stages. We start with the energy level diagram of a
role of silica in cupper abstraction
It is important to differentiate the stoichiometric or empirical formula of a molecular substance from its molecular formula. The former expresses only the relative numbers of atom
