For each bond, show the direction of polarity by selecting the correct partial charges. C-O F-O F-C The most polar bond is ________.
Octet rule For elements in neutral molecules, the number of bonds needed to achieve an octet follows a trend by group, as shown in the following table: Group 4A 5A 6A 7A Number of bonds 4 3 2 1 Number of lone pairs 0 1 2 3 Part A Draw the Lewis structure for SiCl2 Br2. To add the element Si, either double click on any atom and type the element symbol, or access a periodic table of elements from the More button. Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.
