Practicing Ionic Bonding

I. Writing Lewis Dot Structures

a. For each of the elements below, complete the following steps.

1. Write the electron configuration of the element

2. Circle the valence shells of the element

3. Write the Lewis Dot Structure for the element.

Electron Configuration Lewis Dot Structure

Li

Al

O

Ar

N

b. Demonstrate with Lewis Dot Structures and Electron Configurations how the following elements would ionically bond.

Li + F

Be + O

Mg + Cl

3. Determine what charge the following elements would form if they became ions:

Li B O Br P Rb As I S Mg Al Se

d. Without showing the method, determine the chemical formula of the following compounds after they ionically bond. Hint: they will all form neutral compounds!

Ca + F _________________ H + Br _________________

B + P _________________ Al + O _________________

Sr + N _________________ K + N _________________

B + I _________________ Li + Se _________________

Ba + N _________________ In + Te _________________

e. To name binary ionic compounds like those above (those with only two representative elements), simply change the ending of the ion to “ide”. Place their names in the spaces below.

Ca + F _________________ H + Br _________________

B + P _________________ Al + O _________________

Sr + N _________________ K + N _________________

B + I _________________ Li + Se _________________

Ba + N _________________ In + Te _________________

6. Can you determine the chemical formula of these binary ionic compounds?

Magnesium Sulfide __________ Calcium Chloride ___________

Lithium Bromide __________ Gallium Nitride ___________

Strontium Phosphide __________ Aluminum Telluride ___________

7. Cross out the compounds listed below which cannot be ionically bonded.

CaO N₂O RbI K₂Cl Al₂S₃ B₃O₂

SCl₅ PBr Na₂O SeBr BP B₂O
