Compared to ionic bonds, which results from the transfer of electrons between metallic and nonmetallic atoms, covalent bonds result from the mutual attraction of atoms for a “shared” pair of electrons. Covalent bonds are formed between two atoms when both have similar tendencies to attract ...

A Lewis structure is a structural representation of a molecule where dots are used to showelectronpositions around theatomsand lines or dot pairs representcovalent bondsbetween atoms. The purpose of drawing a Lewis dot structure is to identify the lone electron pairs inmoleculesto help determine che...
The Lewis Structure depicts the bonding between individual atoms and molecules through illustrating the presence of valence electron pairs. This type of structure/illustration can be drawn for any molecule held together by not only normal covalent bonds, but also coordinate covalent bonds. A normal co...
Valence Electrons- A valence electron is an electron found in the outer shell of an atom. Valence electrons can participate in the formation of covalent bonds. Covalent Bonding- A covalent bond is a type of chemical bond that involves the sharing of electrons in the valence shell between atoms...

* The carbon atom forms four covalent bonds by contributing four of its valence electrons. It forms 4 bonds with four hydrogen atoms. Thus it gets octet configuration. * Covalency of carbon is 4. * There arenolone pairs on carbon in methane. ...
Lewis Structure : Lewis structure is the representation of a molecule that indicates valence electrons present in a covalent bonds. The lines present in a molecule indicates the bonding electrons and lone pair of electrons shown as dots.
