Question

Name the elements represented by the following symbols:
\[{\text{Hg, Pb, Au, Ag, Sn}}\]

Answer 1

Hint: The elements given in the questions are used in our daily life. \[{\text{Hg}}\] is used in thermometer, \[{\text{Pb}}\] is mixed with graphite in pencils, \[{\text{Au and Ag}}\] are used in jewelry and \[{\text{Sn}}\] belongs to group number 15.

Complete step by step answer:
The name of an element with chemical symbol \[{\text{Hg}}\] is Mercury.
The name of the element with chemical symbol \[{\text{Pb}}\] is Lead.
The name of the element with chemical symbol \[{\text{Au}}\] is Gold.
The name of the element with chemical symbol \[{\text{Ag}}\] is Silver.
The name of an element with chemical symbol \[{\text{Sn}}\] is Antimony.

Additional information:
Atomic number of mercury is 80. It is a d-block element. Mercury is the only metal that exists in the liquid state at standard condition of temperature and pressure. Mercury is used in thermometers, Barometers, manometers, mercury switches and lamps. Atomic number of lead is 82 and is a soft metal. It turns grey, when it is kept open in air due to the formation of oxides. Silver is also called D block element with atomic number 47 and group number 11. It has a very good electrical conductivity. It is known as precious metal and earlier coins made out of silver.Gold belongs to the same group below silver. It is also a precious metal and is very stable and does not react easily with most of the chemicals.
 Antimony belongs to group number 15 that is the nitrogen family. It is a metalloid that is the property of antimony lies in between metals and nonmetals.

Note:
Mercury and its compound are very toxic to handle. If the mercury spills such as while using thermometers in the laboratory do not make any contact. There should be proper ventilation in the area where mercury is being used. Lead is also a very poisonous element and can even cause severe damage to the kidney and brains.
