Metals are typically solids. Solid metals can
range from very hard and tough to bend, like
Titanium, to very soft and easy to bend, like
Gold is one of the softest solid metals, which
is why gold is often mixed with other metals when
gold is used in jewelry. For example, you may have
heard of 18 Carat gold rings, which are rings that
are made mostly of gold (75% gold) but have a
small amount of silver mixed into the gold (25%)
to make the ring tougher.
You may also be interested to know that two
different metals actually exist as liquids at room
temperature: mercury and gallium. Since they are
room temperature liquids, I think that they would
qualify as the softest metals! Check out the
YouTube video below to see how some researchers
are using liquid metals to "print" 3-D structures
that may be used in many high-tech applications,
such as strechable wires.
