Question

What is the number of the group that has the most reactive nonmetals (give number and letter- Ex 1A, 2A, etc.)?​

Answer 1

Answer:

Group 7A

Explanation:

The group 7A elements consists of the most reactive non-metals on the periodic table.

This group is known as the group of halogens. They consist of element fluorine, chlorine, bromine, iodine and astatine.

• The elements in this group have the highest electronegativity values.
• They have 7 valence electrons and requires just one electron to complete their octets.
• This way, they are highly reactive in their search for that single electron.
