How is electro-negativity related to the periodic trends of atomic properties and how does effective nuclear charge, the concept invoked to understand those trends, also help explain the trends in electronegativity should be explained. Concept Introduction: Electronegativity is defined as the ability of an atom to attract the shared paired of electron towards itself. The value of electronegativity depends upon the atomic number of the element and also on the distance between the valence electrons and the nucleus. Periodic trend is defined as the gradation in properties of elements of periodic table as we move along the periods from left to right and as we go down the group from up to down. The periodic trend describes the physical and chemical behavior of the elements in the periodic table. The effective nuclear charge is defined as the charge felt by the valence shell electrons by the nucleus.

Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.

Interpretation Introduction
Interpretation: How is electro-negativity related to the periodic trends of atomic properties and how does effective nuclear charge, the concept invoked to understand those trends, also help explain the trends in electronegativity should be explained.
Concept Introduction:
Electronegativity is defined as the ability of an atom to attract the shared paired of electron towards itself. The value of electronegativity depends upon the atomic number of the element and also on the distance between the valence electrons and the nucleus.
Periodic trend is defined as the gradation in properties of elements of periodic table as we move along the periods from left to right and as we go down the group from up to down. The periodic trend describes the physical and chemical behavior of the elements in the periodic table.
The effective nuclear charge is defined as the charge felt by the valence shell electrons by the nucleus.
