Answer 1

Hey.

Here is the answer.

Gold and Platinum are called Nobel metals . They are highly unreactive in nature in normal room temperature and pressure .

They fall at the last or bottom of the reactivity series . They rarely corrode .

Also, they have very shiny lustre and are very precious .

They can be molded in desired shape delicate shape as they are highly malleable and ductile , so due to these properties they are used for jewellery.

Thanks.
