Note: Lithium with the chemical symbol Li is a silver-white and soft alkaline metal with an atomic number of 3. This element is the lightest metal and the least dense solid element under standard conditions of temperature and pressure. Like other alkali metals, lithium is very reactive and flammable, that's why most of them keep it under industrial oil or petroleum. If there is a cut on it, the cut part will have a metallic polish, but due to its high reactivity, it reacts very quickly with air humidity, the air causes it to corrode, and it turns into a dark grayish silver color and then black. comes.
Due to the high reactivity of lithium, it can never be found as a free element in nature, but always in a part of a chemical compound that is more ionic. Lithium is found in a number of pegmatite minerals.
Nanoparticles are of great interest in both industry and natural sciences due to their wide application. While natural materials have constant physical properties regardless of size, the size of a nanoparticle determines its physical and chemical properties. Therefore, the properties of a material change as its size approaches the nanoscale and the percentage of atoms on the surface of the material becomes significant. The important feature of all nanostructures is that the number of surface atoms in them is more than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, the size of the nanoparticle is considered its most important feature. The range of activity of nanoparticles depends on the nature and shape of the nanostructure. However , if the energy of the nanoparticle field is comparable to the energy of electromagnetic radiation and if within a certain range The wavelength of the chemical reactions in the irradiated materials will cause significant changes, the activity of nanoparticles up to 100 nm will be significant. The surface atoms of nanoparticles are not compensated in terms of energy. In general, the results of nanoparticle energy growth can be expressed as the total energy of atoms on the surface of the particle. The freedom of movement of atoms on the surface of nanostructures is limited and only vibrational movements and the movement of electrons are possible. These two electrokinetic reactions are dependent on each other because the displacement of the electron clouds of the atoms definitely changes the vibrational frequencies of the bonds of the atoms of the nanoparticles . On the other hand, changing the location of valence electrons in the bonds changes the polarity of the bond and the bodies known as supermolecules . In this case, electron transfer to a higher energy level becomes possible.
Conclusion :
Due to the high reactivity of lithium, it can never be found as a free element in nature, but always in a part of a chemical compound that is more ionic. Lithium is found in a number of pegmatite minerals.
