Ionic and Covalent Bonding Quiz Review
1. Compare ionic and covalent bonds by completing the chart below.
Types of Elements
Metals and NonMetals
Electrons are:
Are the atoms an
Non-metals and
2. How does electronegativity play a role in ionic bonding?
In ionic bonding the more electronegative element (non-metal) will pull and
electron off of the metal. The non-metal has a negative charge and becomes an
anion while the metal gains a positive charge and becomes a cation. The
attraction between the positive ion and negative ion forms the ionic bond.
3. What is a cation and anion?
Cation- positive….. PAWsitive 
Anion- negative
4. How are cations and anions formed in ionic bonding?
Ionic: Non-metal pulls electron off metal. Non-metal gains electron becoming
negative (anion) and metal loses an electron becoming positive (cation)
Covalent: more negative element pulls the electrons toward its side, forming
the negative side of the bond
5. Draw a dot structure for calcium and sulfur. Show the charge, formula, and name
the compound.
Will do in class….
6. What are the rules for naming ionic compounds?
Metal goes first, add “ide” to end of non-metal. If the metal is a transition
metal you must include a roman numeral to show the number of valence
electrons on one atom of the transition metal.
7. Explain what happens when sodium bonds to chlorine. How do the two bond and
what is the name of the compound?
In class…
8. What is the difference between the electrons in ionic and covalent bonds?
Ionic bonds electrons are transferred
Covalent bonds electrons are shared
9. When an atom loses an electron it becomes a:
Cation- positive
10. What are the rules to naming covalent bonds?
Put PREFIX to show how many atoms of element are present.
The non-metal that comes first going from left to right across periodic table
goes first in the name. Then add “ide” to the end of the second non-metal.
11. What does the oxidation number tell you?
# of valence electrons
12. What is the chemical formula for calcium bromide? Sodium nitride? Aluminum
In class…
13. Why do elements bond?
To become stable…they want 8 valence electrons in valence shell
14. Name the following N2S3 ? What type of bond is this?
Dinitrogen Trisulfide…covalent
15. What is the formula for calcium fluoride? What type of bond is this?
CaF2….ionic bond
16. What is the chemical formula for magnesium nitride? What type of bond is this?
Ionic bond
17. Name this compound, CaCl2. Is it ionic or covalent?
Calcium chloride….ionic
18. What is the name of PbBr2?
In class… Lead (II) Bromide
19. What is the formula for Titanium (III) Chloride? What is the charge of an atom of
TiCl3…the charge on a Ti atom is +3 because it lost 3 electrons
20. What type of bond would Oxygen and Nitrogen form?
They are both non-metals so covalent!!!!!!!!
Heads Up!
Remember Hydrogen is a non-metal as well!!!!
21. CO is carbon monoxide, in this bond the electrons are:
22. C6H12O6 is the formula for glucose, what type of bond holds this molecule
together? How many atoms of oxygen, hydrogen and carbon are there? How many
elements are in this molecule?
6 atoms of oxygen
12 atoms of hydrogen
6 atoms of carbon
3 elements, oxygen, hydrogen, and carbon
23. What is the oxidation number for halogens? Alkali metals?
Halogens : -1
Alkali metlas: +1
24. In a chemical bond what is shared?
25. Name the following or write the formula:
Sodium bromide
Tetracarbon dioxide
Nitrogen Dichloride
Phosphorus Trifluoride
