Based on their valencies, the subscripts of the ionic compounds formed will be:
- 1 and 1
- 2 and 1
- 1 and 2
- 2 and 2
<h3>What subscripts would you most likely use if the following substances formed an ionic compound?</h3>
A. An alkali metal and a halogen.
An alkali metal and a halogen both have valencies of one.
Therefore the subscripts would be 1.
B. An alkali metal and a non-metal from group 16.
An alkali metal has a valency of 1 and a group 16 non-metal has a valency of 2.
By exchange of valencies, the subscript would be 2 and 1.
C. An alkaline earth metal and a halogen.
An alkaline earth metal has a valency of 2 and a halogen has a valency of 1.
By exchange of valencies, the subscripts would be 1 and 2.
D. An alkaline earth metal and a non-metal from group 16.
An alkaline earth metal has a valency of 2 and a non-metal from group 16 has a valency of 2.
By exchange of valencies, the subscripts would be 2 and 2.
Therefore, the subscripts of the ionic compounds formed will be:
- 1 and 1
- 2 and 1
- 1 and 2
- 2 and 2
