How does electro negativity affect covalent bonds?
Increase in the difference in electronegativity along a bond increases the percent ionic character of the bond (how similar it is to an ionic bond). Small to intermediate differences would result in polar covalent bonds and large differences leads to the formation of an ionic bond rather than a covalent bond.
What type of bond would you expect to be formed between sodium and chlorine?
Typically, a metal and a nonmetal will form an ionic bond. You can also go by electronegativity. The difference in electronegativity can be used to predict the type of bond between atoms. Elements with electronegativity differences between 1.6 and 2.0 form ionic bonds if a metal is involved. Elements with electronegativity differences of 2.0 or greater form ionic bonds.
How would you use electronegativity values to predict if a bond will be principally ionic or covalent?
If the electronegativity difference between two atoms is large (greater than 1.7), the bond is typically considered ionic. If the electronegativity difference is small (less than 1.7), the bond is usually considered covalent. Electronegativity values can help to determine the bond type based on the unequal sharing of electrons between atoms.
Which pair CU and CI or I and CI would have a bond with a greater percent ionic character?
Cu-Cl is more ionic than I-Cl as the difference in the electronegativity is more in the case of Cu and Cl.
Which type of atoms would typically form an ionic bond?
Atoms that differ significantly in electronegativity tend to form ionic bonds. Typically, metals (such as sodium, potassium) will donate electrons to nonmetals (such as chlorine, oxygen) to form ionic compounds.

What would fluorine have to combine with to form an ionic compound?
If fluorine combines with an element such that their electronegativity difference is more than 1.7, then they will form an ionic compound. Example:- Hydrogen fluoride is an ionic compound. Hydrogen has electronegativity of 2.1 and fluorine has 4.0. So, the difference is 1.9. Therefore, it is an ionic compound.

Would you expcet C-S to be an ionic bond?
No The electronegativity difference is only 0.03- so definitely covalent.
What bond would F - F be?
This would be an ionic bond. The electronegativity of Hydrogen is about 2.2 and the electronegativity of Fluorine is about 4.0. The difference is 1.8 which is greater than 1.7, the minimum difference for an ionic bond. Added: Or it is (at least) a very polar-covalent bond. Figures 1.7 or 1.8 are in the 'discussion' range
Which pair CU and CI or I and CI would have a bond with a greater percent ionic character?
Cu-Cl is more ionic than I-Cl as the difference in the electronegativity is more in the case of Cu and Cl.
Would o and o form a polar covalent bond?
The electronegativity difference between Ba (EN 0.89) and oxygen (EN 3.44) is high and you would expect bonds to be ionic. Barium oxide is ionic.
Which type of atoms would typically form an ionic bond?
Atoms that differ significantly in electronegativity tend to form ionic bonds. Typically, metals (such as sodium, potassium) will donate electrons to nonmetals (such as chlorine, oxygen) to form ionic compounds.
What kind of bond would form if fluorine and potassium came in contact?
An ionic bond would form between fluorine and potassium. Fluorine has a high electronegativity and would attract the electron from potassium, leading to the transfer of electrons and the formation of ions, resulting in an ionic bond between the two elements.
What is the nature of the CaCl bond in a molecule of calcium chloride CaCl2 if the electronegativity value of calcium is 1.0 and that of chlorine is 3.16?
The bond between calcium and chlorine in calcium chloride (CaCl2) is considered ionic. This is because of the large electronegativity difference between calcium (1.0) and chlorine (3.16). The higher electronegativity of chlorine attracts the electron pair in the bond closer to itself, resulting in the formation of an ionic bond where chlorine gains electrons from calcium.
Why lithium and magnesium makes covalent compound?
Lithium and magnesium are metals that typically form ionic compounds due to their low electronegativity. However, under certain conditions, they can form covalent compounds when they bond with highly electronegative elements like fluorine or oxygen. In these cases, the difference in electronegativity is not large enough to exclusively result in ionic bonding, allowing for the formation of covalent bonds.
