Answer 1

Hint: As we know that in chemistry chemical symbols are generally used to represent a chemical element. Generally it consists of one or two letters, sometimes for some elements it also has three letters. Now let us see the complete step by step solution to know the chemical symbol of lead and mercury.

Complete step by step solution:
As we have mentioned above symbols are used to represent elements symbolically. The symbol of lead comes from the ancient Roman word "plumbum". In ancient times Romans used lead plumbing as it made the water taste sweet. So, the symbol of get is Pb.
The symbol of mercury comes from its Greek name, hydrargyrum which means "liquid silver". Due to this the symbol of mercury is Hg.
So, from the above we conclude that the symbol of lead is Pb and the symbol of mercury is Hg.
Therefore, we can say that option B is correct.

Additional Information:
-Lead is a chemical element placed in the group 14 of periodic table. It has an atomic number as 82 and atomic mass as 207.2.
-It is soft and malleable and has a relative low melting point.
-It is an amphoteric oxide with oxidation number as -4, -2, -1, +1, +2, +3, +4.
-Mercury is a d-block element, placed in group 12 of periodic table.

Note: Always remember that if a chemical symbol consists of two letters, the first letter is always capitalized and the second letter is written in lowercase. If a chemical symbol consists of only one letter then that letter is always capitalized.
