Question

What is the relation of electronic structure of an atom with its position in the
modern periodic table ?​

Answer 1

Answer:

The position of an atom/element in the periodic table is related to the number of electrons in the outermost shell. In a given column or group, all elements have the same number of electrons in their outermost shells. For example, in group 2, all elements have two electrons in their outermost shell.

Answer 2

Electronic configuration of an atom determines its position in the Periodic Table.

• According to the Modern Periodic Law proposed by Moseley, all chemical and physical properties of elements in the periodic table are functions of their atomic numbers. Hence, the elements in the modern periodic table are arranged in increasing atomic number.
• As atomic number is nothing but the number of electrons in the atom, the configuration of electrons in the shells of the atom gives properties such as size, reactivity and charge.
• These properties which are affected due to the electronic structure of the atom determines its position in the periodic table.
