Molecular Shapes VSEPR Theory From a correct Lewis structure we can get to the 3D 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.

Our 100% solids systems are fast setting for quick return to service. Freedom’s deck system come with 5, 10 and 30 year warranties. . Ionic (Atomic) Radii & Coordination Number (CN). Ionic radius: . 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. Co = Together. The Octet Rule. The octet rule says that all atoms want to have eight valence electrons, like the noble gases.. One way that atoms can follow the octet rule is by giving and taking electrons… ionic bonding. 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).
