Explain how can you calculate the Energetics of Covalent Bonding and the Ionic character?
To calculate the the Energetics of Covalent Bonding and the Ionic character, you need to take into accot the difference in electronegativity of two atoms: Δχ = χB − χA.
What type of bonding is involved in the compound SiF4?
polar covalent - use the electronegativity difference
How is EN used in determining the ionic or covalent character of the bonding between two elements?
Usually ionic compounds are electronegative.
How did Pauling define electronegativity?
Pauling's definition of electronegativity Electronegativity is defined as the attracted force which an atom, bonded by a covalent bond, exerts on the bonded pair of electron responsible for the covalent bonding.
How is electronegativity related to the position of elements on the periodic table and covalent bonding?
The difference in electronegativity between the atoms determines the nature of the bond. The larger the electronegativiity difference the more ionic character it will have, this ranges from polar covalent through to ionic bonding.In valence bond terms the ionic resonance forms become more important and make a bigger contribution as the electronegativity difference increases. The contribution of covalent bonding never really disappears.
What are the rules for determining if a compound is covalent?
The electronegativity difference between the bonding atoms is concerned to determine it ionic behaviour.

Why CuS is covalent compound while CuO is ionic compound?
Not sure about your examples but electronegativity variance is a good rule of thumb for deciding ionic from covalent bonds. Electronegativity variance less than 1.4, generally much less, indicates a covalent bonding. Electronegativity variance greater than 1.4 indicates ionic bonding.
Does ZnS contain a polar covalent bond?
Yes. the bonding is best described as covalent and because of the difference in electronegativity the bond is polar.
Why is the bonding in O2 molecules called pure covalent?
because there is no electronegativity difference between the two oxygen atoms.
Is O2 is an example of a nonpolar polar or ionic?
Non polar covalent bonding. (Both atoms have the same electronegativity)
How does electronegativity influence molecular bonding?
Chemical bonding cannot be solely explained with the concept of electronegativity. According to generality, it is said that a particular compound has a principal ionic character if it exceeds the electronegativity difference of 1.7 in Pauling's scale.
What type of bonding is present in cadmium sulphide?
CdS is about 15% ionic and the balance covalent, based on an equation that curve fits measured ionic character of compounds versus difference in electronegativity.
