Why nonmetals present in group 17 and 16 in the modern periodic table are highly reactive?

Answer»
  • Nonmetals present in group 17 (halogen family) and group 16 (chalcogens) have highly negative electron gain enthalpies.
  • As a result, they readily accept one or two electrons and form anions (X or X2–) that have complete octet.
  • Therefore, nonmetals present in group 17 and 16 are highly reactive.
they are highly reactive bcoz they just need an electron or two to complete their configuration (gp 17 and gp 16 respectively) and to complete their octet they can react with any metal to get an electron.
