Test I. Write if the elements in the compound are metal or nonmetal. Then identify if the bond is
COVALENT, IONIC or METALLIC.
COMPOUND
Example: NaCl
1. PH3
2. Al
3. MgO
4. CaCl2
5. CH4
ELEMENTS
Metal and nonmetal
TYPE OF BOND
ionic
Test II. Draw how the bonds are formed in ionic and covalent bonding.
1. For the ionic bond:
 Write the symbols for each element
and draw a Lewis Dot structure for the
valence shell of each element.
 Draw an arrow (or more if needed) to
show the transfer of electrons to the
new element.
 Write the charges on the ions.
 Write the resulting chemical formula.
2. For the covalent bond:
 Write the symbols for each element
and draw a Lewis Dot structure for the
valence shell of each element.
 Draw the bond structure using
chemical symbols and lines. Use one
line for each pair of electrons that is
shared.
 Write the chemical formula for each
molecule.
FLUORINE + FLUORINE
MAGNESIUM + CHLORINE
Test III. Given the name of the hydrocarbon, give its molecular formula.
HYDROCARBON
Example: heptane
1. nonane
2. decyne
3. octene
4. butene
5. hexane
FORMULA
