Ionic compounds form through the transfer of electrons, while molecular compounds form as a result of electron sharing.

Covalent compounds that contain predominantly carbon and hydrogen are called organic compounds A covalent compound that contains predominantly carbon and hydrogen..One convention for representing the formulas of organic compounds is to write carbon first, followed by hydrogen and then any other elements in alphabetical order (e.g., CH 4 O is methyl alcohol, a fuel).For example, the ionic compound sodium oxalate is comprised of Na + and \(\ce{C2O4^2-}\) ions combined in a 2:1 ratio, and its formula is written as Na 2 C 2 O 4. The subscripts in this formula are not the smallest-possible whole numbers, as each can be divided by 2 to yield the empirical formula, NaCO 2 .

Ionic compounds are composed of positive and negative ions held together by ionic bonds. An Ionic bond is a type of bond that forms between a metal and a non-metal. Molecular compounds are compounds made up of nonmetals.

(b) In contrast, ammonia has a pyramidal structure, in which the three hydrogen atoms form the base of the pyramid and the nitrogen atom is at the vertex.The Stock Method of Naming. An ionic compound is named first by its cation and then by its anion. The cation has the same name as its element. For example, K+1 K + 1 is called the potassium ion, just as K K is called the potassium atom. The anion is named by taking the elemental name, removing the ending, and adding “-ide.”.Formula for Ionic Compounds. When writing the formula of an ionic compound we use the lowest whole number ratio of cations ([+] ions) to anions ([-] ions). If you look at a salt crystal you will see that …
