We use Lewis symbols to describe valence electron configurations of atoms and monatomic ions. A Lewis symbol consists of an elemental symbol surrounded by one dot for each of its valence electrons: Figure 7.9 shows the Lewis symbols for the elements of the third period of the periodic table.
The molecular geometry or shape of IF 5 is square pyramidal while its ideal electron geometry is octahedral. The central I atom in the IF 5 molecule is sp 3 d 2. The F-I-F bond angle in IF 5 is 81.9° while the I-F bond lengths are 184.4 pm and 186.9 pm. Iodine pentafluoride (IF 5) is a polar molecule with net μ=4.81 D.

In the periodic table, elements with the valence-shell electron configuration ns 2 np 5 are located in Group 17, also known as the Halogens. Step 2. These elements include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Step 3. The valence shell of these elements has 7 electrons, with 2 electrons in the s subshell (ns
