The idea that the noble-gas configuration is a particularly favorable one which can be achieved through formation of electron-pair bonds with other atoms is known as the octet rule. Noble gas configuration (in this case, that of neon, s 2 p 6) is achieved when two fluorine atoms (s 2 p 5) are able to share an electron pair, which becomes the covalent bond.

Chemical Bonds Molecular compounds are held together on an atomic level by chemical bonds. Three types of chemical bonds include ionic bonds, metallic bonds, and covalent bonds.The types of chemical bond influence the physical properties of the molecular compounds they form.

This is a small piece of industrially produced pure silicon.It is a light (density 2.328 g/cm 3), gray crystalline substance with strong metallic luster.It is very hard (about as hard as quartz and much harder than most metals), but brittle and not malleable like metals.
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.However, in quantum physics, organic chemistry, and biochemistry, the term molecule is often used less strictly, also being applied to polyatomic ions. In the kinetic theory of gases, the term molecule is often used for any.

A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. These are limited to a single typographic line of symbols, which may include.
Compounds of the boron group elements Salts of M 2+ ions. The ionization energies suggest that the formation of salts of the M 2+ ions might be feasible. At first glance, such appears to be the case, since gallium compounds with the formula GaX 2 (X representing chlorine, bromine, or iodine) can be made, and similar cases occur with the other metals of this group.
