Question

The name copper was taken from Cyprus. Which of the following is true?
A.The name of copper was derived from the place where it was found for the first time.
B.The name of copper was derived from its colour.
C.The name of copper was derived from the name of the scientist who discovered it.
D.The name of copper was derived from a mythological character name.

Answer 1

Hint: Copper \[\left( {Cu} \right)\] is naturally present in the Earth’s crust. Copper is extracted from mines and with time, new methods have been discovered that make the extraction of\[Cu\]. Element copper represented by \[Cu\] falls in the \[{11^{th}}\] group of the \[d - \] block and is known as a transition metal.

Complete step by step solution: The \[d - \] block of the periodic table consists of the elements of the groups 3-12 in which the d orbital is filled in each period. \[d - \] block elements are often known as the transition metals which mainly have three series-\[3d(Sc to Zn),4d(Y to Cd),5d(La to Hg)\],omitting \[\left( {Ce to Lu} \right)\]. The \[d - \] block elements are called the transition metals because of their position in the periodic table between \[s - \] block and \[p - \] block elements. The electronic configuration is \[\left( {n - 1} \right){d^{1 - 10}}n{s^{1 - 2}}\] of the elements.
Copper \[\left( {Cu} \right)\] is a chemical element with atomic number 29. It is reddish-metallic in colour and is soft, ductile and malleable metal with very high thermal and electrical conductivity. It is a good conductor of electricity. It helps in human nutrition. It is used for making various alloys and other metals.
Atomic mass: \[63.54u\]
Electronic configuration: \[\left[ {Ar} \right]3{d^{10}}4{s^1}\]
\[Cu\] forms \[Cu{(OH)_2}\] on reaction with bases.
 When this compound is heated, it reacts with oxygen to give black \[CuO\] . \[Cu\] is not much of a reactive metal and does react with dilute acids under normal conditions.
We must know that copper was found in a place named Cyprus for the first time and it gets its name \['cuprum'\] which means island of Cyprus.

So, the correct answer for the given question is option A.

Note: The half filled and completely filled sets of orbital are relatively more stable than other orbitals. There is a very little energy gap between \[\left( {n - 1} \right)d\] and \[ns\] orbitals. The transition metals and their compounds also exhibit catalytic and paramagnetic behavior. Copper \[\left( {Cu} \right)\] is also a transition metal of the \[d - \] block.
