Document Summary
Chapter 6 reading guide: describe the difference between a shared pair and an unshared pair of electrons a shared pair is two electrons that are involved in forming a bond. Some molecules are represented by two or more lewis structures that are called. Vespr theory helps predict molecular shapes: describe a molecular dipole. If six electrons are shared between two atoms, they form a triple bond: contrast a polar covalent bond and a non-polar covalent bond. In a polar covalent bond two atoms share electrons unequally, while in a non-polar covalent bond two atoms share equally: describe how bond energy is related to the breaking of covalent bonds. Covalent bonds are formed when atoms share one or more electrons. A spring shows the different/changing distances between two atoms, when a stick is defined: describe the energy changes that take place when two atoms form a covalent bond.
