1. What is the best way to determine the electronegativity value of an element?
2. What is the notation for the valence electrons in the element bromine?
3. What are the only elements that naturally have a stable electron configuration?
4. Most atoms have stable electron configurations if they have eight valence electrons in their outermost
energy level. What would the element magnesium have to do in order to get these eight valence electrons?
5. Circle the portions of this statement that are incorrect: The electrons available to be lost, gained, or
shared in the formation of chemical compounds are referred to as valence electrons. For main-group
elements, the valence electrons are the electrons in the outermost s and p sublevels. Group 2 elements
have only one valence electron. All oxygen atoms have 6 valence electrons.
6. How many valence electrons do the halogens have? _________
7. Why are most atoms chemically bonded to each other?
8. Most atoms achieve electron cloud stability by __________________________________.
9. If a potassium atom loses one electron, it will become ______________________________.
10. Describes the formation of an ionic bond.
11. What type of chemical bond would be formed by the bonding of carbon and hydrogen? _____________
12. What type of chemical bond would be formed by the bonding of lithium and bromine? _______________
13. What type of chemical bond would be formed by the bonding of two chlorine atoms to each other? ______
14. How is it possible for two fluorine atoms that each have 7 valence electrons to bond and both have 8 after
bonding?
15. List three elements that would most likely share a pair of valence electrons with a chlorine atom in order to
bond
