Answer 1

Halogens

Step-by-step explanation:

All the elements in Group 17 on the periodic table are classified as halogens. The members of this group are:

• Fluorine
• Chlorine
• Bromine
• Iodine
• Astatine

They are also known as the group VIIA

Their general outer energy level structure is ns² np⁵

• The first four members of the group are common. Fluorine is the most reactive non-metal and iodine is less reactive.
• Due to lack of one electron to complete their outermost shell, they are good oxidizing agents and are univalent.
