Question

Is \[A{l^{3 + }}\] a symbol for aluminium?

Answer 1

Hint: The periodic table plays a vital role. In the periodic table totally of \[118\] elements. In the periodic table there are a total of \[18\] columns and \[7\] rows. The columns are called groups, and \[18\] groups are present in the periodic table. The rows are called periods, and a total of \[7\] periods are present in the table.

Complete answer:
The electrons are filled by the lower energy level to the higher energy level in the atom. In the modern periodic table, elements are arranged in the table depending on the atomic number. In this way, periods and rows are arranged in the modern periodic table.
The atomic number of the element is nothing but the number of electrons or the number of protons. The mass number of the atom is nothing but the sum of the number of protons and neutrons.
The atomic number of aluminium is\[13\].
The atomic symbol of aluminium is \[Al\].
The mass number of aluminium is \[27\].
The stable form of aluminium is \[A{l^{3 + }}\]. In the ground state, an aluminium atom has 13 electrons and for stable purposes it donates three electrons.
The stable cation form of aluminium in \[A{l^{3 + }}\].

Note:
In the world a lot of elements are in various forms. For study and developing purposes, classification has been done. The periodic table is used to study the elements in easy form. If one new element is discovered, it means, based on the physical and chemical property we placed in the periodic table. In general, moving the left to right metallic property of the atom decreases. We move right to left and non-metallic property decreases.
