Question

$Hg$ is the chemical symbol for ____________.
A. Lead
B. Mercury
C. Iron
D. Molybdenum

Answer 1

Hint: Every element in the periodic table has few symbols to represent them. Because always we cannot represent all the chemicals which are going to involve in the chemical reaction with their respective names.

Complete answer:
- In the question it is asked to write the name of the chemical which is going to be represented with Hg.
- Coming to the given options, option A Lead.
- The option A is wrong because Lead is going to be represented with Pb.
- Coming to option C, Iron. It is also wrong because the symbol which is going to be denoted for iron is Fe.
- Coming to option D, molybdenum. It is also wrong because the symbol which is going to be used for molybdenum is Mo.
- Coming to option B, Mercury. It is correct.
- Because the chemical mercury is going to be denoted with a chemical symbol of Hg.

Therefore the correct option is B.

Additional information:
- The atomic number of mercury (Hg) is 80.
- Mercury is also called hydrargyrum.
- Mercury also called quicksilver.

Note:
Mercury is very toxic it may enter through the wounds or at the time of inhalation. Once the mercury is entered into the human body it is going to damage the liver, kidney and the nervous also. But mercury is very useful to measure the temperature by using a thermometer.
