The most likely electronegativity value for the metallic element has been 1.3. Thus, option 1 is correct.
Electronegativity can be defined as the tendency of the atom to attract electrons. The electronegativity of the atom has been dependent on the atomic number and the atomic size.
The periodic table has been arranged in such a way that the metals are arranged in the upper side left side of the periodic table, and nonmetals are arranged towards the lower right side of the periodic table.
According to the Pauling scale, the metals have the electronegativity towards the 1, while the 4 has been the electronegativity for highly electronegative fluorine.
Thus, the most likely electronegativity value for the metallic element has been 1.3. Thus, option 1 is correct.
