Detailed explanation-1: -Gold, for example, is element number 79. Gold bars, gold nuggets, gold dust, coins, and jewelry are all made of the same type of atoms, and they cannot be broken down into anything simpler. The atoms in one piece of gold are identical to the atoms in any other. Therefore, gold is considered an element.
Detailed explanation-2: -Gold is element 79 and its symbol is Au. Though 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.
Detailed explanation-3: -Gold is not a mineral but a native element. Gold (Au) is element 79 on the periodic table. Pure gold is sometimes referred as 24 karats. A karat is a measurement of the purity of gold used in jewelry.
