Chapter 10 Questions (25 Points) 4. Arrange these following elements (CI, Te, Se, Sr, and Ba) in order of increasing electronegativity (lowest first) 5. Off these (H:O, HCI, NHs, CFa, and NaCI), which of the following is the most soluble in gasoline (CaHis) and why? 6. Off these (H:O, BFs, and CH), which has a central atom that often does not obey the octet rule? 7. What is the electron geometry of a compound when the central atom is surrounded by 3 single bonds and 1 lone pair? 8. How many electrons are there in the outer shell of an oxide ion? 9. Classify each of the following bonds as non-polar (pure) covalent, polar covalent, or ionic. A. C-C Pure covalent B. N-F C. K-Br D. O-H 10. Draw the correct Lewis Structures use the VSEPR model to name the molee

Explanation / Answer

Ans 4

On moving from left to right across the Periodic Table, electronegativity of an element increases.

On moving down from top in the Periodic Table, electronegativity of an element decreases.

Cl > Te

Se > Te

Se > Sr

Sr > Ba

In order of increasing electronegativity ( from lowest to highest)

Ba < Sr < Te < Se < Cl
