Most structuresespecially those containing second row elementsobey the octet rule, in which every atom (except H) is surrounded by eight electrons. Generally, these are molecules with central atoms from groups 2 and 13 and outer atoms that are hydrogen or other atoms that do not form multiple bonds. 11 Uses of Platinum Laboratory, Commercial, and Miscellaneous, CH3Br Lewis Structure, Geometry, Hybridization, and Polarity. 1. These additional electrons must be assigned to the central atom. This is acceptable because Xe atoms have empty valence shell d orbitals and can accommodate more than eight electrons. There are three ways of distributing the lone pairs between the axial and equatorial positions and the lone pairs always go on the equatorial positions because these are the least confined. Determine the Electron geometry from the Lewis WebYou will then use the Lewis structure to draw a geometric sketch of the molecule, including bond angles. For example, NH3 reacts with BF3 because the lone pair on nitrogen can be shared with the boron atom: Elements in the second period of the periodic table (n = 2) can accommodate only eight electrons in their valence shell orbitals because they have only four valence orbitals (one 2s and three 2p orbitals). Note, the lone pair takes up more space than the bonding pair, so the bond angle is less then the ideal 120o. We need to recognize that multiple bonds should be treated as a group of electron pairs when arriving at the molecular geometry.
