If I asked you to name a liquid element, you'd probably say 'mercury', which is liquid at room temperature. So are a few other elements, plus just about any element can turn into a liquid if the temperature and pressure are right. Do you know which element is pictured here, yellow as a solid and melting into a red liquid?
Do you know what the pure elements look like in liquid form? Some elements, like mercury, you may have seen as a liquid because that is its usual state. Other liquid elements may be less familiar to you.
