Answer 1

Answer:

Similarities to Halogens

Noble Gas Configuration: Hydrogen can gain one electron to complete its valence shells. Halogens also have seven electrons in their last shell and can gain one electron to gain noble gas configuration. Electronegativity: They also share the same electronegative nature.
