Question

Why are group 17 elements dangerous?

Answer 1

1. The group 17 elements are present in the periodic table and are known as halogens.
2. Halogen is derived from the Greek word “Halo” which means salts and “Genes” which means producing.
3. Halogens are consisting of elements such as Fluorine$\left(\mathrm{F}\right)$, Chlorine$\left(\mathrm{Cl}\right)$, Bromine$\left(\mathrm{Br}\right)$, Iodine$\left(\mathrm{I}\right)$, and Astatine$\left(\mathrm{At}\right)$.
4. Halogen reacts with metals to form salts.
5. Halogens are highly reactive in nature.
6. The gases are toxic in nature, Fluorine is much toxic as they are lethal for all living beings.
7. Astatine is produced industrially and is highly radioactive in nature.
8. The halogen elements are highly reactive in nature and so combine with vigorous and explosive chemical reactions.
