25 AWESOME THINGS YOU<br />
DIDN’T KNOW ABOUT GOLD<br />
by Cielo Panda<br />
Gold was used as a currency of choice in the past, but even though it isn’t used as currency anymore, it still<br />
retains its value. Here are 25 awesome things you didn’t know about gold.<br />
Gold is one of the substances<br />
that are equated with<br />
extreme value. Have you<br />
ever wondered why? Why is<br />
gold considered one of the<br />
most valuable metals in the<br />
universe? One of the reasons<br />
could be because it’s one of<br />
the rarest metals on earth,<br />
but there are other metals<br />
that are even rarer. So what’s<br />
the deal? Well, out of all<br />
the rare elements like silver<br />
and platinum, gold has one<br />
distinction that makes it<br />
stand out—it’s yellowish.<br />
Also it doesn’t react with<br />
other elements so it doesn’t<br />
tarnish. All the others are<br />
grayish. Gold was used as a<br />
currency of choice in the past,<br />

as currency anymore, it still<br />
retains its value. Here are 25<br />
