How do ionic bonds form?
Use your periodic table to draw the electron configuration for the elements below.
Then show how the elements will become “happy” by having full outer shells.
This means these elements must gain or lose electrons.
1. Sodium chloride (NaCl)
-
For sodium to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the sodium atom have a ___________________ ______charge.
(positive/ negative )
- For chlorine to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the chlorine atom have a ___________________ ______charge.
- Now the atoms will have opposite charges and they can form an ionic bond.
2. LiF - Lithium Fluoride
-For lithium to
shell it must ___________________
have a full outer
______
(receive/ give away)
#
electrons. This will make the lithium atom have a ___________________ ______charge.
(positive/ negative )
- For fluoride to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the fluoride atom have a ___________________ ______charge.
- Now the atoms will have opposite charges and they can form an ionic bond.
3. LiCl - Lithium Chloride
For lithium to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the lithium atom have a ___________________ ______charge.
(positive/ negative )
- For chlorine to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the chlorine atom have a ___________________ ______charge.
4.
NaF - Sodium Fluoride
- For sodium
to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the sodium atom have a ___________________ ______charge.
(positive/ negative )
- For fluoride to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the fluoride atom have a ___________________ ______charge.
5.
Now the atoms will have opposite charges and they can form an ionic bond.
NaBr - Sodium Bromide
-
For sodium to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the sodium atom have a ___________________ ______charge.
(positive/ negative )
- For bromine to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the bromine atom have a ___________________ ______charge.
-
Now the atoms will have opposite charges and they can form an ionic bond.
NaI - Sodium Iodide
6)
For sodium to have a full outer shell it must
___________________
______
(receive/ give away)
#
electrons. This will make the sodium atom have a ___________________ ______charge.
(positive/ negative )
- For iodine to have a full outer shell it must ___________________
______
(receive/ give away)
#
electrons. This will make the iodine atom have a ___________________ ______charge.
-
Now the atoms will have opposite charges and they can form an ionic bond.
