The capacity of an element to establish chemical bonds by attracting an electron is measured by electronegativity. The capacity of an atom to attract the shared pair of electrons of a covalent bond to itself is measured by electronegativity, and the shared electrons will be evenly shared. Because of its tremendous capacity to attract a shared pair of electrons, fluorine is the most electronegative element. Fluorine’s electrical structure indicates that it has 5 electrons in its shell and 6 electrons in its 2p orbital. The electrical configuration of fluorine is quite near to that of the ideal. It demonstrates fluorine’s great capacity to attract electrons and establish a perfect electrical arrangement. The capacity of an element to establish chemical bonds by attracting an electron is measured by electronegativity.
