Answer 2

Answer:

group 17 elements are called Halogens

Explanation:

The name "halogen" means "salt-producing". because these elements will readily react with alkali metal and alkaline earth metals to form halide salts. The halogens all have the general electron configuration ns 2 np 5 , giving them seven valence electrons. They are one electron short of having the full outer s and p sublevel, which makes them very reactive.
