Describe covalent bonding and how molecular compounds are formed. covalent bonding occurs when atoms share electrons to attain the electron configuration of a noble gas. Atoms in the bond count the two electrons in the bond toward their octet. These compounds are called molecular compounds.

Covalent compounds, also known as molecular compounds, are formed from the sharing of valence electrons. These electrons are shared to fill the outermost s and p orbitals, thus stabilizing each atom in the compound. If you examine the word, covalent, it means with valence electrons. These compounds are formed when two non metals combine chemically.

Oct 01, 2016  · Recall that covalent compounds are those that involve more than one atom bonded together by the sharing of electrons. You’ll know for certain that you are dealing with a molecular compound if only nonmetals are present.; To name a covalent compound, you need the molecular formula, knowledge of the prefixes used for naming, and a way to look up the name of an element.

For example, the molecule carbon tetrachloride is a non-polar covalent molecule, CCl4. It's melting point is -23°C. By contrast, the ionic solid NaCl has a melting.
