Correct Answer: Gallium

Solution : The correct answer is gallium .

Most metals can be easily alloyed with gallium, particularly those that melt at lower temperatures. Gallium has a high boiling point, making it ideal for measuring temperatures that would cause a thermometer to evaporate. It is a chemical element with the symbol Ga and atomic number 31 and is part of Group 13 on the periodic table. Gallium shares similarities with other metals in the same group, such as thallium, indium and aluminium.
