Question

What is the symbol used to designate the element iron.
$(i){\text{ I}}$
$(ii){\text{ In}}$
$(iii){\text{ Ir}}$
$(iv){\text{ Fe}}$
$(v){\text{ F}}$

Answer 1

Hint: The modern periodic table has assigned some unique symbol for every element which is known till now. Iron is also one of the elements which has got a unique symbol for its representation in chemical equations. The above mentioned symbols represent various elements. Some of them are gas while some are present in solid state.

Complete answer:
Presently, there are $118$ elements present in the modern periodic table which have some unique representation. This unique way of representing them with the help of symbols is useful while writing a chemical equation. Iron also has got some unique symbols for its representation universally. From the given options we will check each symbol and find out which symbol is meant for iron. At the very first we have$(i){\text{ I}}$. This is a symbolic representation for the iodine element. Then we have$(ii){\text{ In}}$. This is a symbol used to represent the Indium element. Then we have $(iii){\text{ Ir}}$ . This is a symbolic representation for the Iridium element. Then we have $(iv){\text{ Fe}}$ . This symbol is used to represent the iron element. The atomic number of iron is $26$. It is a metal. Then moving ahead we have $(v){\text{ F}}$. This is a symbolic representation for fluorine gas. Therefore we have concluded that the symbolic representation of the iron element is $Fe$.

Note:
Every element has a unique symbolic representation in the modern periodic table. No two elements can have the same symbolic representation. Iron is a $d - $block element. It is present after manganese and before cobalt in the modern periodic table. It is lustrous and a hard metal. It gets corroded easily when it comes in contact with moisture.
