Gold as everyone knows is a noble metal sought after by everyone. By being noble means it is resistant to chemical reactions like corrosion by air and water combination. The answer to the question why it has the colour it has lies in electronic configuration of gold atoms. Its electronic configuration is [Xe] 4f14 5d10 6s1 where Xe stands for Xenon. The outermost orbitals are 5d and 6s. There is one electron in the outermost shell. In the geometric structure, atoms are arranged in a particular config And the lone electrons present the 6s orbitals are diffused in the lattice… Read More »Why Gold has the colour it has??
