Find an element from the halogen group and noble gases group and tell how it is used in everyday life.

See below a complete explanation.

Explanation:

1. Halogen group

The halogen group is the group number 17 of the periodic table. The elements of this group or family are:

Fluor, FChlorine, ClBromine, BrIodine, IAstatine, At; andTennessine, Ts.

The most widely used of those elements in everyday life are fluor, chlorine, and iodine.

Fluor is used in toothpastes, to combat the formation of caries.Chlorine is used in household cleaning agents as it is a disinfectant due to its ability to kill germs.Iodine is incorporated into table salt because it fights a disease called goiter.

2. Noble gases group.

The noble gases group is the group number 18 of the periodic table.

These elements are the most stables of all the  118 elements.

Therefore, they do not react normally.

The elements of this group or family are:

Helium, HeNe, NeArgon, ArKripton, KrXenon, XeRadon, RaOganesson, Og

The most used in everyday life are helium and neon.

Helium: It is widely used to inflate party ballons. Since it is considerably ligther that air, helium ballons float in the air.Neon: It is use for illumination. Inside a glass tube, the electricity makes neon glow. For intstance, there are a lot of neon signs in Las Vegas.

Nonmetals usually react by gaining electrons
