Question

Is the following symbol of element incorrect? Give the correct symbol.
Aluminium \[{\rm{AL}}\]

Answer 1

Hint: As we know that the symbol of every element represents on the basis of its characteristics such as shape, size, reactivity, taste. Scientists named every element in the periodic table by its name to recognize easily.

Complete step-by-step answer:
Aluminium is an element which is the member of Group \[13\] in the periodic table. It is represented by its symbol \[{\rm{Al}}\].
Aluminium is named by scientists on the basis of its characteristic taste. In the ancient time, its name was discovered from the alum (potassium sulphate) which has a bitter taste so aluminium was named as Alumen.
The symbol was given to every element because it is easy to write in a periodic table. Therefore, according to the rule of representing symbol of elements-
The symbol should be started in capital with the same letter as in the name of the element.
The second letter should be in small letters.

Therefore, the given symbol of aluminium is incorrect. The correct symbol is \[{\rm{Al}}\].

Note: Aluminium has atomic number \[27\] and it is the second member of group \[13\](also known as Boron family) because it has three valence electrons which enter in the outermost shell of the atom.
