Which one of the following metals has both malleability and ductility properties:

The correct answer is Au.

Key Points

• ​Gold is element 79 and its symbol is Au.
• The name is Anglo Saxon, gold originated from the Latin Aurum, or shining dawn, and previously from the Greek.
• It's abundance in the earth's crust is 0.004 ppm. 100% of gold found naturally is isotope Au-197.
• Gold is the most malleable of all metals. It can be drawn into a wire of single-atom width, and then stretched considerably before it breaks.
• Gold has only one stable isotope, 197 Au, which is also its only naturally occurring isotope, so gold is both a mononuclidic and monoisotopic element.
