How to Write Covalent Compound Formulas. Writing covalent compounds involves the use of Greek prefixes. They are listed in the table to the right. The prefixes are used to indicate the amount of each atom in the compound. The first element never uses the prefix mono-, but does use all others. If no prefix is used before the first element's name, there is only one of that element. The second.
First of all, to name a covalent compound, it helps to know what a covalent compound is. Covalent compounds are formed when two or more nonmetal atoms bond by sharing valence electrons. Valence electrons are the outermost electrons of an atom. Elements want to fill up their electron orbitals, or shells, with electrons, so they will bond with.For some background information, a covalent bond is a bond in which two or more elements SHARE electrons to become stable. In retrospect, ionic compounds TRANSFER electrons to make ions and become stable. Covalent formulas or covalent molecules are compounds that only (for simplicity) contain NON-METALS. For example, potassium chloride, KCl NOT covalent as it contains a metal.Start studying Compounds, chemical formulas, and covalent bonds.

The chemical formulas for covalent compounds are referred to as molecular formulas because these compounds exist as separate, discrete molecules. Typically, a molecular formula begins with the nonmetal that is closest to the lower left corner of the periodic table, except that hydrogen is almost never written first (H 2 O is the prominent exception).

When there are covalent compounds, they are to be written as molecular formulas. This is because each compound is a separate molecule. The first element of a covalent compound is written completely, but the second element is written with a suffix “ide” in the end. For example, nitrogen dioxide. Write the first element in a symbolic way.
These are examples of covalent bonds and covalent compounds. Covalent compounds also are known as molecular compounds. Organic compounds, such as carbohydrates, lipids, proteins, and nucleic acids, are all examples of molecular compounds. You can recognize these compounds because they consist of nonmetals bonded to each other.
In the conventional presentation, bonds are designated as ionic when the ionic aspect is greater than the covalent aspect of the bond. Bonds that fall in between the two extremes, having both ionic and covalent character, are classified as polar covalent bonds. Such bonds are thought of as consisting of partially charged positive and negative.

Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals.An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.

To write chemical formulas, acquaint yourself with chemical symbols, most easily found on the periodic table of elements. The periodic table is a chart of all the known elements, and it often includes both the full name of each element and its symbol, such as H for hydrogen or Cl for chlorine.
