Complete the following using the word bank above. Words can be used more than once.
An ionic bond occurs between a ______________ and a _____________________ and involves
the _______________ of electrons. A metal _______________ electrons to become a positive
________________ and a nonmetal ______________electrons to becomes a negative
________________. A covalent bond occurs between a _________________ and a
_________________, and involves ___________________ electrons. In a covalent bond,
nonmetals can share one pair of electrons (_______________ bond), two pair of electrons
(__________ bond), three pair of electrons (___________ bond), or even four pairs of electrons
(quadruple bond). A metallic bond involves ____________moving electrons surrounding metal
atoms, also referred to as a ______________________. These electrons give metals it
characteristic properties.

Metallic Bonding
Define these properties of metallic properties:
1) Sea of electrons
2) Ductility
3) Malleability
4) Thermal conductivity
5) Electrical Conductivity
Covalent Lewis Structures
Draw the following Lewis structures for the covalent compounds, and then identify both the
molecular and electron geometry.
1. CBr4
3. SiS2
5. H2S
2. NH3
4. BI3
6.HCl
Mixed Lewis Structure Drawing Practice
Draw the Lewis structures for the following compounds. Make sure to recognize if the
compound is ionic or covalent because the Lewis structures look different. If Ionic identify the
cation and anion by placing the appropriate charges with the ions and if covalent, identify the
molecular and electron geometry.
1. Sr3P2
3. PCl3
2. SeO2
4.Cs2O
