Most metals are not. a) ductile. b) good conductors of heat and electricity. c) liquid at room temperature. d) malleable.

C) liquid at room temperature

Metals possess strong forces between their atoms because their electrons are delocalized. The result is that metals are able to conduct heat and electricity. Moreover, the planes of ions are able to slip over one another, making metals malleable and ductile. However, the melting point of metals is relatively high and the only metal liquid at room temperature is mercury (Hg).
