Hint: Electronegativity is the ability of an atom in a molecule to draw the mutual pair of electrons towards itself. Since it is just a tendency, it is a dimensionless property. It simply denotes the net product of atoms' tendencies to draw bond-forming electron pairs in various elements.
Complete answer:
Electronegativity is the ability of an atom in a molecule to draw the mutual pair of electrons towards itself. Since it is just a tendency, it is a dimensionless property. It simply denotes the net product of atoms' tendencies to draw bond-forming electron pairs in various elements.
On many scales, we calculate electronegativity. Linus Pauling produced the most widely used scale. The most electronegative element is fluorine, which has a value of 4.0, and the least electronegative element is cesium, which has a value of 0.7. When we pass through a time of the current periodic table from left to right, the nuclear charge increases and the atomic scale decreases, so the value of electronegativity increases. In the current periodic table, the atomic number increases as we step down the group. The nuclear charge rises as well, but the impact of the rise is mitigated by the addition of one shell. As a result, as we step down the group, the value of electronegativity decreases.
An electronegative factor prefers to accept electrons rather than lose them. As a result, they would have a strong ionisation potential.
In basic terms, ionisation energy is a calculation of how impossible it is to remove an electron from an atom or ion, or how likely an atom or ion is to surrender an electron. The loss of an electron normally occurs in the chemical species' ground state.
Hence option B is correct.
Note:
Metals have a lower electronegativity than nonmetals, which is a common finding. As a result, metals are electropositive, whereas non-metals are electronegative. Period two elements have different properties than their respective group elements due to their small scale and higher electronegativity value.
