ANSWER 1 = There are a wide range of low melting alloys available. Yet some are restricted in their use based on their brittleness, toxicity, and reactive qualities. Some of these elements are bismuth, gallium, tin, indium, zinc, cadmium, tellurium, antimony, thallium, mercury and lead.
ANSWER 2 = In other words, the material has the ability to deform under compressive stress. A malleable material is one in which a thin sheet can be easily formed by hammering. Gold is the most malleable metal. In contrast, ductility is the ability of a solid material to deform under tensile stress.
ANSWER 4 = Mercury can be solidified when its temperature is brought to its freezing point. However, when returned to room temperature conditions, mercury does not exist in solid state for long, and returns back to its more common liquid form.
ANSWER 5 = Non-metals are poor conductors of heat and electricity except Graphite. They do not possess metallic luster. Non-metals are not sonorous, they do not produce a ringing sound. Non-metals possess no malleability.
ANSWER 3 = The elements can be classified as metals, nonmetals, or metalloids. Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid).
