Question

What is the name given to group $17$ elements? Why are they called so?

Answer 1

We have to know that, he gathering 17 components incorporate fluorine $\left( F \right)$ , chlorine $\left( {Cl} \right)$ , bromine $\left( {Br} \right)$ , iodine $\left( I \right)$ and astatine $\left( {At} \right)$ from the top to the base. They are classified as "incandescent lamps" or halogens. Since, they give salts when they respond with metals.

Complete answer:
We have to know that the group $17$ elements are called halogens. The halogens are situated on the left of the respectable gases on the occasional table. These five poisonous, non-metallic components make up group $17$of the intermittent table and comprise of fluorine $\left( F \right)$ , chlorine $\left( {Cl} \right)$ , bromine $\left( {Br} \right)$ , iodine $\left( I \right)$ , and astatine $\left( {At} \right)$ . In spite of the fact that astatine is radioactive and just has brief isotopes it acts like iodine and is frequently remembered for the halogen bunch. Since the halogen components have seven valence electrons, they just require one extra electron to shape a full octet. This trademark makes them more responsive than other non-metal gatherings.
The halogens are forms from diatomic particles (of the structure ${X_2}$ , where $X$ indicates a halogen iota) in their basic states. The bonds in these diatomic particles are non-polar covalent single bonds. In any case, incandescent light promptly consolidates with most components and are never seen uncombined in nature.
Then the chlorine $\left( {C{l_2}} \right)$ was the principal halogen to be found, trailed by iodine $\left( {{I_2}} \right)$ , bromine $\left( {B{r_2}} \right)$ , fluorine $\left( {{F_2}} \right)$ , and astatine $\left( {At} \right)$ , found toward the end. Together, these words consolidate to signify "salt-previous", referring to the way that halogens produce salts when they respond with metals. Halite is the mineral name for rock salt, a characteristic mineral comprising, basically of sodium chloride.

Note:
We have to know that, the halogens are likewise significant in day by day life, regardless of whether it be the fluoride that goes in toothpaste, the chlorine that cleans drinking water, or the iodine that works with the creation of thyroid chemicals in one's body.
