Explain about the salient features of metals.

Answer»
  • Metals comprise more than 78% of all known elements. They are present on the left side of the periodic table. 
  • They are usually solids at room temperature. [Mercury is an exception (Hg-liquid), gallium (303 K) and cesium (302 K) also have very low melting points]. 
  • Metals usually have high melting and boiling points. 
  • They are good conductors of heat and electricity. 
  • They are malleable and ductile, and also can be flattened into thin sheets by hammering and drawn into thin wires.
