Question

Which of the following element has lowest melting point? (A) Cr (B) Fe (C) Ni (D) Cu

Tardigrade Admin · Accepted Answer

Cu has lowest melting point because it has lowest enthalpy of atomisation (i.e., heat required to break the metal lattice to get free atoms) among the elements. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/e3718df4f2d815218a873f828426af74-.png" />
