What is it caled when... A family of unreactive elements whose atoms do not gain, lose, or share valence electron

The family of unreactive elements you are referring to is called the noble gases. These elements include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). Noble gases are known for their stability and lack of reactivity due to their full valence electron shells.

To find this answer yourself, you can follow these steps:

1. Begin by searching for "unreactive elements" or "elements that do not gain, lose, or share valence electrons" on a search engine.

2. Review the search results to identify the family or group of elements that meet this criteria.

3. The noble gases, as mentioned above, will be listed as the group of elements that do not readily react or form compounds due to their stable electron configurations.

By following these steps, you can easily find the answer to your question.
