Question

Name a 'metal' which has the following properties.

Metal
A. Is a liquid at ordinary temperatures.
B. Has a low boiling point but does not float on water.
C. Is a light, soft metal which can be cut with a knife.
D. Does not give a note on striking.

Answer 1

Mercury has those following properties it is a liquid at ordinary temperatures, has a low boiling point but doesn’t float, etc.

Answer 2

The metal that is a liquid at ordinary temperatures is mercury (Hg), while a light and soft metal easily cut with a knife could be sodium (Na) or potassium (K). Lead (Pb) is known not to give a note when struck.

Step-by-step explanation:

The metal described, which is a liquid at ordinary temperatures and has low boiling point but does not float on water, is mercury (Hg). Mercury is unique among metals as it remains in liquid form at room temperature. For the metal that is light, soft, and can be cut with a knife, an example would be sodium (Na) or potassium (K), which are alkali metals known for these properties. Lastly, lead (Pb) is often considered a metal that does not 'ring' or give a note on striking because it is relatively soft compared to other metals like bell metals which have a high tin content and can resonate.
