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. Noble gases have low reactivity because they have full electron shells. WebImportant Notice: Media content referenced within the product description or the Download Ebook Chapter 5 Electrons In Atoms Answer Key various topics, facts and methods. Valence electrons are all arranged in different orbitals or shells and are mostly negatively charged particles. Covalent Bonds Shared electrons located in the space between the two nuclei are called bonding electrons. Moving through the elements in the periodic table, each atom has one more electron than the last because the number of electrons is the same as the atomic number. Chemical bonds are extremely important to chemists, scientists, and everyday people. Without the electrons, the atoms will be positively charged. 3 Why is understanding bonding important?
