Chapter 3 had gone over covalent bonding, metallic bonding, ionic bonding and galvanization. Covalent bonding happens when atoms share pairs of electrons, the atoms will covalently bond with other atoms in order to gain more stability, and that is gained by forming a full electron shell. Along with that, atoms share their valence electrons, which can fill the outermost shell and gain stability. Although in order to be stable the atoms must follow the Octet Rule, which requires the atoms in the molecule to have eight valence electrons. The atoms would either gain or lose the electrons to become stable enough to be in the molecule. As atoms become smaller, this causes causes electrons to become closer to the nucleus for a greater charge. With that, two atoms that share electrons and the electronegativity levels are zero; it is called a nonpolar covalent bond. Although there are dipoles, which are partially negatively charged along with being positively charged also. Also, the Rank bond polarity is based on location of atoms in the periodic table. Lots of importance is attached to the electronic structures of noble gases that have eight electrons in their outer energy levels. When other atoms react, they try to achieve noble gas structures; it is possible for atoms to reach these stable structures by sharing electrons to give covalent bonds. With that, these gas structures are thought as being a “desirable” thing for an atom to have. Metallic Bonding happens when a strong…
