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.
A Galvanic cell or voltaic cell or electrochemical cell is a system in which a spontaneous chemical oxidation- reduction happens and makes electrical energy.
what is magnetic moment
Alkyl ligands form metal carbon σ bonds. Usually they occur in conjunction with other organic ligands or CO, but may be achieved on their own, as in tungsten hexamethyl (1), and
what is allotropy
Q. Determine the Number of neutrons? Isotopes of an element can as well be specified by writing the mass number of the isotope following a hyphen after the name of the element.
history of this reaction.is any ligand is needed for the reaction?
variation of cnductivigy with temperature
Q. Occurrence of group 13 element? Both boron and aluminium have a high affinity for oxygen, so neither of them is found native. Boron occurs principally in the earth's crust a
Classification of polymers - Synthetic polymers The polymers that are prepared in the laboratories are known as synthetic polymers. These are as well described as manmade polym
Q. Use values of Δ f H and Δ f G to evaluate the standard molar reaction enthalpy and the thermodynamic equilibrium constant at 298.15 K for the oxidation of nitrogen to form a
