The most common type of bond formed by carbon is a covalent bond. In most cases, carbon shares electrons with other atoms (usual valence of 4). This is because carbon typically bonds with elements which have a similar electronegativity. Examples of covalent bonds formed by carbon include carbon...
The smallest representative unit of any covalent chemical compound is a single molecule, in which some number of atoms are connected through the sharing of valence electron pairs. A molecule is polar if it has a net dipole momen...
Polar vs. Nonpolar Covalent Bonds: Examples | What are Polar & Nonpolar Covalent Bonds? from Chapter 1 / Lesson 5 2M Learn about polar vs. nonpolar covalent bonds. Discover polar and nonpolar covalent bond examples, and examine how to predict polar vs. nonpolar bonds. Related...
Three onion type double carbon cages (consisting of an inner sp3-hybridized C60 buckminsterfullerene skeleton and an outer larger carbon cage with icosahedral symmetry, with covalent bonds between the carbon atoms of the 5-membered rings) are described and their strain energies are discussed: (i) ...

Covalent Bonds in Water The hydrogen atoms in the H2O water molecule form the same kind of covalent bond as in hydrogen gas but with the oxygen atom. The oxygen atom has six electrons in its outermost electron shell, which has room for eight electrons. To fill its shell, the oxygen atom...
