Answer:

  • Hydrogen and the halogens are all non-metallic elements, but they behave very differently. Hydrogen often combines with negative, non-metallic ions to form acids and organic molecules. Halogens, on the other hand, only form negatively-charged ions that react with metallic, positive ions to make ionic compounds like salts.
  • While hydrogen is a single element with unique properties of its own, the halogens are a collection of elements.
  • In its simplest natural state on Earth, hydrogen is a diatomic, molecular gas (H2). This gas is odorless, colorless and flammable. Of the halogens, only fluorine and chlorine are gases (F2 and Cl2, respectively) naturally on Earth. Both are toxic and fluorine is greenish in color, while chlorine is green. The other halogens are liquid (bromine) or solid (iodine and astatine) in nature.
  • One of the main underlying causes of the differences between hydrogen and the halogens is the size of the atoms involved. Hydrogen atoms are the smallest of all the elements, consisting of only one proton and one electron. Halogen atoms, in contrast, can be quite large.
  • A closer look at these elements, however, reveals that hydrogen must remain separate from the halogen elements.

Hope it helps :)
