Explain the process of chemical bonding. Explain how the difference in electronegativity (distance apart on the periodic table) affects the likelihood of the reaction and the strength of the bond. List and explain 3 of the “rules of thumb” you learned to use the periodic table. For example (do not use this one) how an element is more electronegative as you move toward the right. What is the chemical formula for the compound that results from the reaction of Hydrogen and Sulfur? Describe in your own words how you arrived at this formula. What is the Strong Force? What are Nuclear Fission and Fusion, describe each in your own words.

Chemical bonding is the process by which atoms combine to form molecules or compounds, driven by the quest to achieve a stable electron configuration, often fulfilling the octet rule. Atoms bond by sharing electrons (covalent bonds), transferring electrons (ionic bonds), or through metallic bonding. Covalent bonds involve the sharing of electron pairs between atoms, leading to molecules with distinct shapes and properties. Ionic bonds, on the other hand, occur when electrons are transferred from one atom to another, resulting in positively and negatively charged ions held together by electrostatic attraction.

The difference in electronegativity between atoms significantly influences the type and strength of chemical bonds formed. Electronegativity is a measure of an atom's tendency to attract electrons towards itself when it forms a chemical bond. When the electronegativity difference is small, atoms tend to share electrons equally, forming nonpolar covalent bonds; when the difference is large, electrons are transferred, leading to ionic bonds. A moderate difference results in polar covalent bonds, where electrons are shared unequally, creating partial charges. Thus, greater electronegativity differences generally increase the likelihood of ionic bonding and increase bond strength, as the electrostatic attraction between ions is stronger.

Three useful rules of thumb for interpreting the periodic table include: (1) Atomic size decreases across a period from left to right because additional protons increase the nuclear charge, pulling electrons closer; (2) Atomic size increases down a group because additional electron shells are added, making atoms larger as you move down; (3) Electronegativity increases across a period from left to right, as atoms have a greater tendency to attract electrons due to increased nuclear charge, and decreases down a group because additional electron shells weaken the attraction of the nucleus for bonding electrons.

The chemical formula resulting from the reaction of hydrogen and sulfur is H₂S. This formula indicates that two hydrogen atoms combine with one sulfur atom. I arrived at this formula by understanding that sulfur typically forms two bonds to complete its octet, and hydrogen can only form one bond. Thus, two hydrogen atoms are needed to satisfy sulfur's valence requirement, resulting in H₂S. This compound is commonly known as hydrogen sulfide and exhibits a bent molecular shape due to lone pairs on sulfur affecting the molecule’s geometry.

The Strong Force, also known as the nuclear or strong interaction, is the fundamental force that binds protons and neutrons together within the atomic nucleus. It is the strongest of the four fundamental forces, but it operates only over very short distances, approximately the size of atomic nuclei. The strong force is essential for nuclear stability, preventing positively charged protons from repelling each other strongly.

Nuclear fission is a process where the nucleus of a heavy atom, such as uranium-235, splits into smaller nuclei, releasing a large amount of energy, along with neutrons and gamma radiation. This process is harnessed in nuclear power plants to generate electricity. In contrast, nuclear fusion involves two light atomic nuclei, such as isotopes of hydrogen (deuterium and tritium), merging to form a heavier nucleus, releasing an even greater amount of energy. Fusion is the process that powers the sun and other stars. While promising as an energy source, controlled nuclear fusion remains a significant scientific challenge and is still under development.
