Concept explainers
Interpretation:
The electronegativity values of metals in comparison with nonmetals has to be chosen from the given options.
Concept Introduction:
Close relationship between ionic and covalent bonding models becomes apparent if the bond polarity and electronegativity is considered. Electronegativity is the measure of relative attractive for the shared pair of electrons in a bond. Higher the electronegative value for an atom, the more it attracts the shared pair of electrons towards itself.
In Periodic table, when moving from left to right in a period, the electronegativity value increases. While moving from top to bottom within group, the electronegativity value decreases. Nonmetals have higher electronegativity values than metals. Metals gives electrons and nonmetals accepts electrons.
