Unit 3: Formation of ionic and metallic bonds Key unit competence: Describe how properties of ionic compounds and metals are related to the nature of their bonding 3.1. Introduction Activity 3.1 Look at the pictures above and answer the following questions. Record your answers and discuss them in your groups. 1) Observe carefully pictures A, B and C and suggest the similarity between them. 2) What can you say about the chloride and sodium ions in the pictures above? 3) What holds the chloride
laying out the equations describing an orbital spaceflight in which the landing position of the spacecraft is specified. It was the first time a woman in the Flight Research Division had received credit as an author of a research report. In 1962 NASA prepared themselves for the orbital mission. Katherine would have a moment to remember. She would be doing something that would make her well known for. The work that was required Katherine was well for. Orbital flight had required the construction of
the nature of the chemical bond and its appliance to the clarification of the structure of complex substances. By working on the nature of the chemical bond, Pauling presented the idea of orbital hybridization. In chemistry, hybridisation is the concept of intermingling atomic orbitals into new hybrid orbitals suitable for the pairing of electrons to form chemical bonds in valence bond theory. Pauling also studied the correlation between ionic bonding and covalent bonding. Here, Pauling's electronegativity
