Best answer
Correct Answer - Option 3 : Gallium

The correct answer is Gallium.

  • Gallium melts when kept on the palm.
  • It is because they have a very low melting point and just the heat in our palm can melt them easily.
  • The temperature where the solid substances completely melt and produce a liquid or gaseous substance is known as the melting point.
  • Cesium also melts on hand palm.
