Chemical Bonds

Drawing Ionic and Covalent Bonds

Ionic Bonds (Metal & Nonmetal)

Draw the Bond

Between Potassium and Oxygen

EXAMPLE

Potassium & Oxygen

Ionic Bonds (Metal & Nonmetal)

1. Complete Lewis Dot Structures of Each Atom Involved

EXAMPLE

Potassium & Oxygen

K O

Ionic Bonds (Metal & Nonmetal)

2. Organize the DOTS of the Lewis Dot Structure so you can better show the TRANSFER of electrons. EXAMPLE

Potassium & Oxygen

K O

Ionic Bonds (Metal & Nonmetal)

3. Use arrows to show the transfer of electrons.

METALS LOSE electrons

NONMETALS GAIN electrons

EXAMPLE

Potassium & Oxygen

K O

Ionic Bonds (Metal & Nonmetal)

4. Continue adding ATOMS and arrows until each atom has a full outer shell.

EXAMPLE

Potassium & Oxygen

K OK

Ionic Bonds (Metal & Nonmetal)

5. Write the full chemical equation showing the ions created, as well as the final product.

K+ + O2- K2O

EXAMPLE

Potassium & Oxygen

K OK

Ionic Bonds (Metal & Nonmetal)

6. Name the compound created using the naming rules.

K+ + O2- K2O

Potassium Oxide

FINISHED EXAMPLE

Potassium & Oxygen

K OK

K+ + O2- K2OPotassium Oxide

Covalent Bonds (2 Nonmetals)Draw the Bond for H2S

EXAMPLE

H2S

Covalent Bonds (2 Nonmetals)1. Complete Lewis Dot Structures

for each atom involved

EXAMPLE

H2S

H H S

Covalent Bonds (2 Nonmetals)2. Move DOTS and atoms around

for organization and efficiency.

Think Symmetry!

Think AHEAD

EXAMPLE

H2S

H S H

Covalent Bonds (2 Nonmetals)3. Draw loops showing the sharing of

electrons.

Each ATOM hasits own loop

Each loop showsa complete outershell

Each H has 2 electrons (full)

The S has 8 electrons (full)

EXAMPLE

H2S

H S H

Covalent Bonds (2 Nonmetals)4. Show another picture using

lines to represent PAIRS of shared electrons.

1 pair = 1 line

2 pairs = 2 lines

EXAMPLE

H2S

H S H

H S H

Covalent Bonds (2 Nonmetals)5. Name the compound created

using the naming rules.

EXAMPLE

H2S

H S H

H S H

Dihydrogen Monosulfide
