Magnesium
It occurs mainly as insoluble carbonates, sulphates and silicates, in crystal rocks. It is the sixth most abundant element following calcium. Magnesium occurs as dolomites (MgCO 3 .CaCO 3 ), magnesites (MgCO 3 ), epsomite (MgSO 4 .7H 2 O). It is further represented by common ba..
Compounds of Magnesium and Calcium
Magnesium and calcium form dipositive ions. They form compounds with many non-metals. The compounds are generally ionic. Unlike the salts of alkali metals, those of magnesium and calcium are not always readily soluble in wat..
Formation of alkyl magnesium halides
Magnesium reacts with haloakanes in ether medium, to form alkyl magnesium halide, commonly called as the Grignard's reagent. Grignard's reagents are very useful synthetic reagents in organic chemist..

. Magnesium does so. Beryllium forms covalent compounds while magnesium forms ionic compounds. With water, beryllium carbide gives methane while magnesium carbide gives acetylene. BeO is amphoteric in nature while MgO is basi..
Formation of magnesium nitride
>Two magnesium atoms donate two electrons to each nitrogen atom while one magnesium atom donates one electron to each of the nitrogen atom. Hence, an ionic bond is formed. Magnesium and nitrogen, thus, attain stability by gaining the octet state. The conditions necessa..

>) and potassium nitrite (KNO 2 ), carbon dioxide (CO 2 ) and carbon monoxide (CO). The properties of compounds are absolutely different from the properties of the elements that constitute the compound. For instance, hydrogen is combustible and oxygen is a supporter of combustio..
Action with magnesium (formation of Grignard reagent)
When a solution of an alkyl halide in dry ether is treated with magnesium, an alkyl magnesium halide is formed. Alkyl magnesium halides, generally, represented as RMgX, are known as Grignard reagents. These have great synthetic applications and are useful in the p..

Due to their small size and higher charge density these elements form stable complexes. Of these, beryllium and magnesium have maximum tendency to form complexes. For example, beryllium form complexes of the type [BF 4 ] 2 - ..
Characteristics of compound
Compounds always contain a definite proportion of the same elements by mass. Water as a compound, always contains hydrogen and oxygen in the ratio 1:8 by mass. The properties of compounds are totally different from the elements from which they are formed. For exam..

Math is no more a problem at all for me, an hour tutoring everyday with an online tutor is helping me to get good grades
Their whiteboard is great. Online tutoring from this site is as good as like face to face tutoring and the great thing is I dont have to spend a lot.
I could help my daughter with studies but now since she studies through this site, I dont have to. This is truly great idea !
Well developed topics, very good content and a comprehensive list of lesson plans. Really niice.
