Question

Does gold have a variable valency?
please give a short answer ​

Answer 1

• The atomic number of Gold is 79.

• The symbol of Gold  is Au.

• Gold has two valencies ⇒ 1 and 3.

Trivalent gold is the more stable of the two, but the element in both valence state is capable of forming complex ions, particularly the trivalent state.

Answer 2

Answer:

Yes, gold has a variable valency 1 and 3

    Gold atomic number = 79

its symbol = Au

there is a more stable valency of gold is 3 then 1 because due to de stabilization of the 5 d -orbital, two electrons from the 5d- orbital are also lost forming a +3 oxidation stage .

Some elements vary in there ability to interact with other elements depending of the nature of the reaction is called variable valency.
