As the radius of an atom increases, the attraction between the positively charged nucleus and the negatively charged outer level electrons decreases. This is because the outer level electrons are farther away from the "home base." So, as atomic size (radius) increases, the nucleus has less and less a hold on those outermost electrons. For this reason, cesium (Cs, atomic #55) has very large atomic size and very low electronegativity. Fluorine (F, atomic #9) has very small atomic size but large electronegativity.

When electrons are shared between atoms, the nuclei of both atoms experience attraction towards the electrons and vice versa. At a certain distance, the attraction is maximal because the repulsion between the nuclei is small while the attraction of each nuclei to the electrons is strong. Thus, the atoms are held together by their attraction to the shared electrons.

transferring or sharing electrons
These are the chemical properties.
Electronegativity is the attraction of an atom for the shared pairs of electrons.
When electrons are shared between atoms, the nuclei of both atoms experience attraction towards the electrons and vice versa. At a certain distance, the attraction is maximal because the repulsion between the nuclei is small while the attraction of each nuclei to the electrons is strong. Thus, the atoms are held together by their attraction to the shared electrons.
is an attraction between atoms so electrons are shared in a physical bond
Sharing of electrons between two atoms is called covalent bonding.
The atom with the greater attraction for shared electrons in the molecule is the more electronegative atom.
bond
That attraction is described mathematically by Coulomb's Law.

Atoms in column 7 of the Periodic Table have 7 electrons in their outer shell. Atoms are most stable when they have 8 electrons in their outer shell. So atoms of elements in column 7 have a strong attraction for 1 electron. Flourine being the smallest atom in that column has the strongest attraction for 1 electron.
