WebThe electrons orbit within orbital shells each shell leads to another row or period within the periodic table. A crude (and simplified) representation of such a bond between two atoms might look like this: There are several types of chemical bonds, the one shown above is representative of a covalent bond, where electrons are shared between atoms. Another application of this law is the study of crystal structures, as the ions of the crystals arrange themselves so that the electrical forces are balanced. They have to make sure that the paint is homogenous because if it was heterogeneous when being applied, the paint would not go on well. If these high-energy electrons which make up the bulk of the energy stored in atoms were not transferred, they would not perform the role of powering cell functions.

In later chapters, we will develop the concepts introduced here to explain why the only compound formed by sodium and chlorine is NaCl, an ionic compound, whereas neon and argon do not form any stable compounds, and why carbon and hydrogen combine to form an almost endless array of covalent compounds, such as CH4, C2H2, C2H4, and C2H6. The electronic arrangement of the first 18 elements is listed below: The electrons present in the outermost shell of an atom are known as the valence electrons. The understanding of the electron has allowed for a better understanding of some of the most important forces in our universe such as the electromagnetic force. The electrons of the outermost energy level determine the energetic stability of the atom and its tendency to form chemical bonds with other atoms to form molecules.
