Question 19

Which family name applies to the metallic members of group 1, with hydrogen excluded from that classification?

  1. Alkali metalsBonne réponse
  2. Halogens
  3. Alkaline-earth metals
  4. Transition metals

Explication

The metallic members of group 1 are alkali metals; hydrogen occupies the column but is not classified as one. The similarly named family in the next column is a different set, so hydrogen must not be used to broaden the metallic label.
