Gold is a soft metal with a number of interesting physical properties. Gold is also used in medicine. The chemical symbol for Gold is Au. Aluminum surfaces can be highly reflective. Due to this, silver is used for the contact points in all printed circuit boards and is also used in electrical conductors as a coating. The hardness of any given material is usually determined by pressing a carefully shaped indenter onto a surface under a load, resulting in a permanent plastic deformation. When gold is accessible in mass, it has a somewhat reddish-yellow colour. 2. It can also conduct heat with relative ease. After surface characterization, the biological behavior assessment was conducted regarding human gingival fibroblasts (hGF) and . This makes it one of the higher atomic number elements that occur naturally. Gold is a good conductor of electricity and heat.
