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.
Theory of Meta directing group The substituent, S takes electrons from para and ortho positions. So, m-position becomes a position of comparatively high electron density and fu
Calculate the Value for the Standard Molar Reaction Entropy? Derive an expression for the standard molar reaction entropy of a reaction that can be used to calculate its
Entropy (S) is a molecular 'disorder', or more precisely 'the number of microscopic arrangements of energy possible in a macroscopic sample'. Entropy depends strongly on the state
Mesomeric forms are the possible locations of electrons at a single instant, if you get what I mean. Like, an adjacent double and single bond in a molecule. The resonance form, how
Which one of the following is considered as the main postulate of Bohr's model of atom: (1) Protons are present in the nucleus (2) Electrons are revolving around the nucleu

Electronegativity may be described as the power of an atom to attract electrons to itself in a chemical bond. It is the most important chemical parameter in calculating the type of
