Answer 1

Answer:

a and b are correct answer

Answer 2

Due to its in-reactive nature, it is shiny after thousands of years.

Explanation:

• It is because gold is inert just like noble gases.
• The atomic number of gold is 79 making it the element having a higher atomic number.
• Gold metal has a heavy nucleus and it has high density due to a greater number of electrons revolving in the orbits.
• It does not react with air and therefore it remains stable for a longer period of time.
