The
The ability that is possessed by an atom to attract the bonding pair of electrons towards itself is known as electronegativity. The electronegativity decreases while going down the group and increases while moving from left to right in the period.

- In the molecule carbon tetrachloride, the electrons in each C-Cl sigma bond would be: closer to the chlorine atom because chlorine is more electronegative than carbon. located directly between the carbon and chlorine atoms. 13 closer to the carbon atom because carbon is less electronegative than chlorine closer to the carbon atom because carbon has the larger radius and has a greater gravitational pull.arrow_forwardTo draw a Lewis Structure, start with the atomic symbol in the middle, then put dots around the symbol until all of the valence electrons are represented. Try to envision a box around the atom symbol, and the electrons on each side of the box. The valence electrons should be drawn around the element symbol one on each side before pairing the electrons up. The maximum number of electrons that could be on one side of a Lewis Structure is two, and the maximum number of electrons around an element symbol is eight. To figure out how many valence electrons each element has, use the Periodic Table. Remember, the number of valance electrons for Group A elements is equal to the Group A number the element is in on the Periodic Table. Use the data you collected in Table 1 to a draw Lewis structure model to show the formation of any one of the compounds you assembled, then explain the model you drew. Remember, you should be explaining and supporting your answers by referencing and citing the…arrow_forwardDecide whether the Lewis structure proposed for each molecule is reasonable or not.
