Question

Metals are solid except:
(a) Bromine
(b) Mercury
(c) Sodium
(d) Lead

Answer 1

Hint : Metals are the elements present in the periodic table having various properties like good conductors of heat and electricity. They are lustrous and solid in nature and have a metallic bond.

Complete Step By Step Answer:
Metals: Metals are the elements present in the periodic table having various properties like good conductors of heat and electricity. They are lustrous and solid in nature and have a metallic bond.
All the metals present are solid in nature. There is only one exception that is Mercury which is liquid in nature.
Hence, Metals are solid except Mercury.
Hence, the correct option is (b) Mercury.

Additional Information:
The elements of the periodic table are divided into three parts:
(a) Metals: Metals are the elements present in the periodic table having various properties like good conductors of heat and electricity. They are lustrous, malleable, ductile and solid in nature and have metallic bonds.
(b) Non-metals: Non-metals are the elements present in the periodic table and are bad conductors of heat and electricity. They are brittle in nature. They are neither lustrous nor malleable nor ductile.
(c) Metalloids: Metalloids are the elements in the periodic table which are having the properties of metals as well as non-metals. Silicon, Germanium are the few examples of metalloids.

Note :
Non-metals are soft, except diamond, an allotrope of carbon. Also, another exception of non-metals is graphite, non-metals are bad conductors of electricity, and it is also an allotrope of carbon, a good conductor of electricity. These are exceptions of non-metals.
