about metallic bonding

. C, Si Non metal Ge Metalloids Sn, Pb Metals 5. Property of catenation One of the most remarkable properties of carbon is to form bonds with itself thus, forming chains of carbon atoms. This property of forming bonds with atoms of the same element is called ..

Trends in Chemical Reactivity - As in the case of S, the important oxidation states observed for Se and Te are also 2, +2, +4 and +6. The chalcogenide dianions (E 2 - ) exist only in their compounds with the most electropositive elements. By and large, chalcogens with the exception of polonium, dis..

. Thus the formula of the sulphate is Al 2 (SO 4 ) 3 . 2) The element with atomic number 12, has a configuration of 2, 8, 2. Thus it has a valency of +2 and is a metal. So its oxide has an electrovalent bonding. 3) All the elements in group VIIA have the same number of valence el..

Question: Explain the formation of an ionic compound between a metal and a non metal by transfer of electrons with Mg as the metal and chlorine as the non-metal to illustrate your answer. Give the reaction that occurs. Answer: Magnesium, whose atom..

Magnesium, whose atomic number is 12, has 2, 8, 2 configuration. Its valence shell has two electrons. The electronic configuration of chlorine (At. no. 17) is 2, 8, 7. It has seven valence electrons. Since, magnesium has two electrons in excess of the neon configuration (2, 8), and chlorine is one..

Carbon is the eleventh most abundant element in the earth's crust by mass. Carbon is the first member of group IVA and a typical non-metal. Carbon exhibits allotropy and shows maximum catenation. Carbon occurs both in free state as diamond, coal etc. and also in the combined fo..

Ionization - 'The process of conversion of a neutral atom into charged ions to complete its octet is known as ionization.' In this process, the neutral atom loses or gains electrons. The particle that loses electrons gains positive charge equal to the number of electrons lost, while the particle th..

>Two important resources of ammonia are ammonium salts and ammoniacal liquor obtained by the destructive destruction of coal . Ammonia and ammonium compounds are highly soluble in water and do not occur as minerals in large quantities. The NH 3 molecule has a large dipole moment, and this is consis..

Aldehydes differ from ketones in their oxidation reactions. Aldehydes are easily oxdised to carboxylic acids on treatment with common oxidising agents like nitric acid, potassium permanganate, potassium dichromate etc. Aldehydes are easily oxidised to carboxylic acids containing the same number of ..

Nitrogen does not easily combine with other elements under ordinary conditions. A molecule of nitrogen is diatomic. These two atoms have combined by mutually sharing three pairs of electrons (Fig.12.7). ..
