Determine whether the following pairs of elements can form ionic compounds. (Ionic or Not Ionic)

1 - iron and cholrine

2 - oxygen and magnesium

3 - fluorine and sodium

4 - potassium and sulfur

5 - nitrogen and iodine

6 - lithium and calcuim

1 - Yes ionic

2 - Yes ionic

3. Yes ionic

4. Yes ionic

5. Yes Non ionic.

6. No compound formed.

Explanation:

The first 4 form strong ionic bonds because the electrons in the metals easily lose their valency electrons to form positive ions and the non-metals form negative ions.

5. the nitrogen forms covalent bonds with the iodine but the cluster of iodine atoms tend to repel each other. The bonding is not strong so this compound is explosive.

6. these do not react with each other.

Hello!

Let's solve this!

To form ionic compounds we need that one of the elements is a metal and the other a nonmetal. In this way the polarities will be distributed.

Let's analyze each of the options:

1 - iron and cholrine: forms ionic bonds because one of the elements is metal and the other is not metal.

2 - oxygen and magnesium: forms ionic bonds because one of the elements is metal and the other is not metal.

3 - fluorine and sodium: forms ionic bonds because one of the elements is metal and the other is not metal.

4 - potassium and sulfur: forms ionic bonds because one of the elements is metal and the other is not metal.

5 - nitrogen and iodine: both elements are non-metals, they do not form an ionic bond.

6 - lithium and calcuim: the two elements are metals, they do not form an ionic bond.
