The first ionization energies of the given halogen atoms and the electronegativity of the fluorine tom has been given. The electronegativity values for the given halogens, with respect to the given formula, are to be calculated. These values need to be further compared with the stated electronegativity values for the given compounds. Concept introduction: Electronegativity can be defined as the measure of the tendency of an electron to attract the shared pair of electrons towards itself. It is directly proportional to the difference between the ionization energy and the electron affinity value for any given case. To determine: The electronegativity values of the given halogens; a comparison of these values with the values in the text.

The percent ionic character of a bond between elements A and B may be approximated by the expression %IN = 100[1 - e^(-1/4(XA - XB))], where XA and XB are the electronegavities for the respective elements. What is the the percent ionic character of the interatomic bonds for Fe2O3? What type of bonding would you expect in Fe2O3?
Note: Use 1.8 for the electronegativity for Fe and 3.5 for the electronegativity for O.
Although I3- is a known ion, F3- is not. (a) Draw the Lewis structure for I3- (it is linear, not a triangle). (b) One of your classmates says that F3 - does not exist because F is too electronegative to make bonds with another atom. Give an example that proves your classmate is wrong. (c) Another classmate says F3- does not exist because it would violate the octet rule.Is this classmate possibly correct? (d) Yet another classmatesays F3- does not exist because F is too small to make bonds tomore than one atom. Is this classmate possibly correct?
Fluorine lies between oxygen and neon in Period 2.Where as atomic sizes and ionization energies of these three ele-ments change smoothly, their electronegativities display a dra-matic change. What is this change, and how do their electron configurations explain it?
