Binary is composed of substance...

Binary is composed of a substance whose molecules consist of atoms of two parts. Individual atoms, each molecule can vary, but must belong to only two elements, isotopes, even if the items are allowed. Binary compounds in the definition, some of the simplest compounds in all of nature, but also some of the principal as well as organic and inorganic...

Patterns of Chemical Bonding

Only a few elements on the periodic table are satisfied with their arrangement of electrons. This is due to an imbalance between the perceived positive and negative forces of attraction involved in the atom. Collage may be seen as a form of atoms undergo correction, resulting from the electronic configuration as stable as possible a full shell. This pattern is known Asthe octet rule. It is so called because the second row elements, and who need to fill eight valence electron shells. This is a golden rule, and there are many exceptions to this,...

How ionic compounds Workstation

How ionic compounds Workstation All ionic compounds are made up of tiny crystalline structures, which consist of positively charged particles called cations and negatively charged particles known as anions. In an ionic substance. Cations and anions to form a grid band that is very hard and brittle when you are in a solid state, ionic compounds are good electrical conductors because their ions can not move much. In an ionic liquid or substance which was dissolved in a polar solvent, however, is an ionic compound the ions are separated and allow...

Examples of Covalent Bond

If we encounter the world, we have a huge lack of knowledge of the structures around the world in one easy movement unit aggregation is the difference between the atoms. Electromagnetic force to hold atoms together to form molecular compounds that come into an even larger molecules and polymers that are resistant as possible. This complexity reduction is likely that the electromagnetic forces between charged particles. Etching of atoms turns to pity, or to sell the source of electrons to create a network of molecules possible. Bond between...

Ion anhydrous barium chloride

Ion anhydrous barium chloride is the chemical compound with the formula BaCl2. He is one of the most important water-soluble salts of barium. Like other barium salts, is toxic and gives a flame yellow-green. It is also hygroscopic. Anhydrous barium chloride in combination with other water-soluble barium is highly toxic. Sodium sulfate and magnesium sulfate are possible antidotes, because they form a solid insoluble BaSO4 Barium sulfate, which is not toxic. First, let's look at their peril: Eye contact may cause conjunctivitis l Contact...

Organometallic compounds

Organometallic compounds are highly reactive metals are used in basic and reducing agents. The key to understanding the chemical bond in compounds isoball principle is used. Organometallics plays an important role in other areas such as chemical and biological analysis. Depending on the nature of the organic compound, the nature of the link may vary depending on the type of ionic or covalent. There are also a number of complex linkages that characterize the coordination of the metal and organic binders, organic binders such as must always bind...

Classification of Crystals

The crystals are classified into four types: (I) atomic crystals (Ii) ionic crystals (Iii) covalent crystals (Iv) molecular crystals This classification is based on the nature of forces and bonds between atoms, ions or molecules constituting the crystal. (I) atomic crystals Examples of these crystals are metals, so they are also called metal crystals. They are made of atoms packed and held together by metallic bonds. In metals, the valence electrons move freely in the crystal lattice and said that from an electron gas, where the positive...

Ionic bonding Vs. metallic bonding

Ionic bonding Vs. metallic bonding As proposed by the American Chemical GNLewis, atoms are stable when they contain eight electrons in its valence shell. Most atoms have fewer than eight valence electrons in its shell (with the exception of noble gases in Group 18 of the periodic table), therefore are not stable. These atoms tend to react with each other to become stable. Thus, each atom can achieve a noble gas electron configuration. This can be done by forming ionic bonds, covalent or metallic. Ionic bond Atoms can gain or lose electrons...
