What is special about gold element?
Gold is one of the densest of all metals. It is a good conductor of heat and electricity. It is also soft and the most malleable and ductile of the elements; an ounce (28 grams) can be beaten out to 187 square feet (about 17 square metres) in extremely thin sheets called gold leaf.

How many electrons does a gold atom have?
Gold atoms have 79 electrons and 79 protons with 118 neutrons in the most abundant isotope. Under standard conditions gold is a shiny yellow metal. It is very dense and heavy, but also fairly soft.
How is gold classified as a transition metal?
It is classified as a transition metal. Gold atoms have 79 electrons and 79 protons with 118 neutrons in the most abundant isotope. Under standard conditions gold is a shiny yellow metal. It is very dense and heavy, but also fairly soft. Gold is the most malleable of the metals meaning that it can be pounded into a very thin sheet.
