Explain why gold is not attacked by oxygen, moisture and acids.
Answers
Answer: It is because Gold reacts with the halogens, particularly in the presence of moisture. Gold reacts with various oxidizing agents at ambient temperatures provided a good
is present to lower the redox potential below that of water.
Explanation:
Answer:
The Correct Answer is mentioned below
Explanation:
Gold is inert because the nucleus of gold is so dense that electrons must travel at the speed of light. The 6s electrons in gold are less accessible for bonding and have a different energy than many reactants. This gold renders inert.
The lack of reactivity of gold is explained by relativistic effects. Gold has a massive enough nucleus that its electrons must travel at near-light speeds to avoid falling into the nucleus. This relativistic effect is applicable to orbitals with significant density near the nucleus, such as s and p orbitals. Because these relativistic electrons gain mass, their orbits decrease. As the s and (to a lesser extent) p orbits constrict, the remaining electrons in the d and f orbitals are better screened from the nucleus, causing their orbitals to expand.
