combining basic elements

Combination of Elements - Atoms of elements combine to form molecules of compounds. This combination can occur in two ways: either by electrovalent bonding or covalent bonding. In all chemical reactions it is the electrons from the outermost shell o..

Atoms of elements combine to form molecules of compounds. This combination can occur in two ways: either by electrovalent bonding or covalent bonding. In all chemical reactions it is the electrons from the outermost shell of an atom that are involved in interacti..

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). ..

. Metalloids are the elements, which have properties that lie between those of metals and non-metals, e.g., arsenic, antimony, etc. Molecules of elements may consist of single atom, two atoms, or even more. All the hundreds of thousands of compounds existing, and produced by man..

All alkaline Earth metals combine with hydrogen upon heating to form ionic hydrides, MH 2 , excepting beryllium. Some basic characteristics of hydrides are: MgH 2 is covalent in nature while all other hydrides i.e. CaH 2 , SrH 2 , BaH 2 , are ionic. Calcium hydride is al..

Borax is slightly hydrolyzed in solution. As boric acid is a weak acid, the solution is alkaline in nature...

Ammonia molecule has a strong tendency to donate its lone pair of electrons of nitrogen to other molecules. Thus, it acts like a strong Lewis base. In aqueous solutions, NH 3 ionizes in accordance with the reaction...

Nitrogen combines with certain compounds on strong heating. For example, With calcium carbide: Calcium cyanamide, aluminium nitride and magnesium nitride hydrolyze on boiling with water to give ammonia...

The force which holds together the ions, atoms and molecules in a chemical substance is called as chemical bond. It is the same force which makes substances combine with each other in many different ways to give newer products. The combining tendency of atoms to form chemical bo..

Symbol: C Atomic number : 6 Atomic mass: 12 (most common isotope) Electronic configuration: 1s 2 ,2s 2 ,2p 2 Position in the periodic table: Period II Group IV Carbon occurs in the free state as well as combined state. The following schematic chart shows the occurrence of carbon in va..
