Answer:

Gold is an unreactive (inert) metal which is not readily combined with other elements and will not oxidise. Unlike Zinc which is a more reactive metal and can easily react with other elements and oxidise to Zinc Oxide. Why was silver used to make coins in the past?

Explanation:

im a geek does that help

Gold is the element having atomic number 79 and is represented as Au. It occurs naturally in pure form. Gold belongs to the transitional group.

The element with atomic number 30 and represented as Zn is called zinc. It is a brittle metal of grayish colour and belongs to the 12th group.

Gold occurs natively uncombined but zinc does not because Gold is an unreactive metal that does not get easily oxidised. Whereas zinc is a reactive metal and gets easily oxidised.

Gold is an oxidizing agent and do not give electrons easily and remains as an element.

Zinc is reactive metal than gold and is capable of giving electrons.

Therefore, gold is native and zinc is not.
