Question

This group of elements sit along a stair step line on the periodic table and have properties of both metals and non-metals:

  1. Radioactive elements
  2. Halogens
  3. Transition metals
  4. Metalloids

hintHint:

Metalloids have properties of both metals and non metals.

The correct answer is: Metalloids


    • A radioactive element is one with an unstable nucleus, which radiates alpha, beta or gamma radiation and gets converted to a stable element.
    • Halogens are in the 17th group of periodic table chemically related elements.
    • Transition metals are mainly d block elements with multiple oxidation states.
    • Metalloids are a group of elements sit along a stair step line on the periodic table and have properties of both metals and non-metals.
