<em>It is beneficial because it provides stronger support for the evidence related to the discovery</em>
<u>Answer:</u> <em>The correct answer is the second option that is given with shows it is beneficial.</em>
<u>Explanation:</u>
The discovery of an element whose properties are known from before would make it easier for the scientists to know the properties of elements and its uses after the discovery of element. 
Since the elements’ properties are already known as element that possesses these properties and will look forward to find that and once the element is found the element can be named and can be used directly, since its uses are already known.

All I can say is that Mercury is a liquid at room temperature, and liquids will very slowly evaporate at room temperature. This is because the molecules have a relatively low energy at room temperature (since room temperature is very low compared to boiling point). The boiling point of mercury is 356.73 degrees Celsius, and room temperature is only about 23 degrees Celsius, so the evaporation rate at room temperature would be little to nothing.
