Write the Lewis electron structure for each species. Now here the given molecule is TeBr4 and it contains tellurium atom (Te) and bromine atoms (Br). Since tellurium is less electronegative than bromine, assume that the central atom is tellurium. xs There is still one more bond that you must use in the structure. Add the remaining 12 electrons to the S atoms (as three lone pairs per S atom) to give the following structure: 6. The fact that SO 2 is a resonance hybrid of two Lewis structures is indicated by writing a double-headed arrow between these Lewis structures, as shown in the figure above. &zF The central metal is denoted by using its chemical symbol from the Periodic Table. Example: Draw the Lewis structure for boron trifluoride, BF 3. endobj These outer bromine atoms are forming an octet and hence they are stable. endobj HWo> The valence electron configurations of the constituent atoms of a covalent compound are important factors in determining its structure, stoichiometry, and properties. The only common substances that have a lone pair on a C atom are CO and CN-. Valence electrons given by tellurium atom: Tellurium is a group 16 element on the periodic table. The stability of lewis structure can be checked by using a concept of formal charge. Now in the above sketch of TeBr4 molecule, put the two electrons (i.e electron pair) between each tellurium atom and bromine atom to represent a chemical bond between them. !\ While selecting the atom, always put the least electronegative atom at the center. In TeBr2, each Br a . We can say that the number of lone pairs around any atom when added to the number of electrons participating in bonding equals to the number of valence electrons in the atom. endstream Thus, the process for step one is 2 x (# of H atoms) + 8 x (# of most other atoms) = valence electrons needed.
