sodium atomic spectra

When the atomic vapours from a sample are placed in the path of white light from an arc lamp, it absorbs the light of certain characteristic wavelengths and the light of other wavelengths get transmitted. In such conditions a series of dark lines on a white background are formed. This is..

Atomic Spectra - A spectrum is an assembly of energy levels in the form of radiations emitted by an atom in its excited state. Every atom gives discontinuous line spectra. Each line in the spectra corresponds to a specific wavelength and i..

Hydrogen is the simplest element with its atom having only one electron. Hence, the atomic spectrum of hydrogen has played a significant role in the development of atomic structure. In the emission spectrum of hydrogen, when an electric discharge is passed through hyd..

Emission and Absorption Spectra - One can understand atomic spectra if one knows the concept of atomic energy levels. The movements of electrons from one level to another causes the spectra. The work of a spectoscopicst is to find the energy levels ..

Sodium atom Sodium ion It is silvery white. It is colourless It reacts readily with water to displace hydrogen from it It does not react with water It is extrenely active and poisonous It is inactive and non-poisonous. ..

One can understand atomic spectra if one knows the concept of atomic energy levels. The movements of electrons from one level to another causes the spectra. The work of a spectoscopicst is to find the energy levels of an atom from the measured..

Aryl halide undergo 'Wurtz Fittig reaction' when heated with alkyl halide in the presence of sodium in anhydrous ether. Halogen atom is replaced by alkyl group. ..

When sodium chloride is formed the sodium atom donates an electron to the chlorine atom to form an electrovalent bond. Hence in the process: Sodium atom loses an electron and becomes positively charged (Na + ). Chlorine atom..

In the formation of sodium chloride, ..

The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom (Fig. 2.1..
