write down the properties of diamagnetic materials

(e.g., TiO 2 , NaCl, C 6 H 6 ) are weakly repelled by external magnetic fields. This property is shown only by those substances which contain fully-filled orbitals i.e., no unpaired electrons is presen..

Michael Faraday discovered that a specimen of bismuth was repelled by a strong magnet. Diamagnetism occurs in all materials. These materials are those in which individual atoms do not possess any net magnetic momen..

On the basis of their magnetic properties different materials are classified as: Diamagnetic substance Paramagnetic substance Ferromagnetic substan..

Matter exists in several phases. If we look at all objects around us, we perceive that some materials have a definite shape and occupy a definite amount of space or volume. We call these materials solids and we can name many objects that are solids. We say that solids have a def..

Polyethylene has a low softening point of 383K and a low specific gravity of 0.22. The material is tough flexible highly insulating water resistin..

By the study if electronic configuration of transition metals it is understood that they generally contain one or more unpaired electrons in the (n-1)d orbital. Due to these unpaired electrons they behave as paramagnetic substances. These substances are attracted by the magnetic field. The transit..

Neoprene is superior to natural rubber because of the following properties: Neoprene is non-inflammable but natural rubber is inflammable Neoprene is resistant to oils, organic solvents, petrol and grease. Natural rubber swells and rots in contact with these materials N..

Pure hydrogen peroxide is a pale-blue syrupy liquid with a bitter taste. It is soluble both in water and alcohol. Its density is 1.469 g/mL. It melts at 272.4 K (- 0.7C) and boils under 760 mm of Hg pressure at 423.2 K (150C) with violent decomposition. However, it can be distilled under..

Uses of Sulphur Dioxide - It is a powerful germicide and insecticide and hence it is used a household fumigant. It can bleach delicate fibres. It undergoes easy liquefaction and vaporization and hence it is used as refrigerent in cold storage plants. It is used in the manufacture of sulphuric acid ..

They are deflected by electric and magnetic fields. The deflection is less compared to that of b particles, because a particles are heavy. They affect a photographic plate and cause fluorescence on striking a fluorescent material. They ionise the gas through which they pass. The..
