Answer:
They're never found as individual elements in nature because they are so reactive.
Explanation:
Halogens are a highly reactive group of elements. They are usually found combined in nature.
- Because each of the elements has seven electrons in the outer shells of their atoms the elements are all univalent and also acceptors of electrons.
- They are all non-metals and oxidizing agents.
- This makes the elements in this group highly reactive and combine readily with other species in nature.
