Hypothetical radius (size) of an ion (. cation. or anion). Calculated values from the bonding distances. CN. Number of one kind of the bond forming ions (atoms) surrounding the other, which are forming the first direct bonding. IB Topics 4 & 14. Text:. Ch 8 (all except sections 4,5 & 8). Ch 9.1 & 9.5. Ch 10.1-10.7. My Name is Bond. Chemical Bond. PART 5: Giant Covalent Structures, Metallic Bonding & Physical Properties. Metals. Look at the Periodic Table…. 75% of elements are metals!. Metals. They can vary a lot…. General Properties of Metals. Dense. Malleable. Ductile. Good conductors of heat and electricity. Shiny Lustre. CHEMICAL BOND – A force that holds two or more atoms together as a unit. Individual atoms will naturally bond together to achieve a lower energy state (to be more stable). 3B-1 (of 42). TYPES OF BONDS. Molecular Shapes. VSEPR Theory. From a correct Lewis structure, we can get to the 3-D shape using this theory.. VSEPR stands for . v. alence . s. hell . e. lectron . p. air . r. epulsion.. The theory is based on the idea that e- pairs want to get as far away from each other as possible!.

A business insurance policy that protects the employer in case of any loss of money or property due to employee dishonesty. What is the Federal Bonding Program?. What makes this program great?. Metallic Bond – the force that holds metal atoms together. Metals do not form covalent bonds with one another because they do not have enough electrons in their outer shells to form stable octets..
