Do ionic bonds have a greater or lesser electronegativity difference between them than a covalent bond?
The difference in electronegativity between two elements bonded into a compound by ionic bonds is almost always greater than the difference in electronegativity between two elements bonded into a compound by covalent bonds.
Why do the elements S and O form a covalent bond?
If the electronegativity difference between two elements is above 1.7, then ionic bond is formed between these two. If the electronegativity difference is below 1.7, then they form covalent bond. In the case of sulphur and oxygen the electronegativity difference will be below 1.7
Is N-O ionic or covalent?
Definitely covalent. The electronegativity difference isn't great enough for a bond between Nitrogen and Oxygen to be ionic. In order for a bond to be Ionic, the electronegativity difference must be 2.7 or greater. The electronegativity difference of N and O is merely .4. Not even close! The further apart on the periodic table two elements are, the greater the electronegativity difference. Electronegativity GENERALLY increases going up and to the right on the table. There are, however, some cases in which exceptions can be noted, but they are not too common.
Are covalent bonds made up of metals and nonmetals?
Two elements will form ionic compound if the difference in electronegativity between the two elements is above 1.7 and two elements will form covalent compound if the difference in electronegativity between the two elements is below 1.7 Metals and non-metals will form generally ionic compounds.
What compound has a greater difference in electronegativities of its members NaCl or KCl?
KCl has a greater difference between the electronegativity of the two elements present.
Do ionic bonds have a greater or lesser electronegativity difference between them than a covalent bond?
The difference in electronegativity between two elements bonded into a compound by ionic bonds is almost always greater than the difference in electronegativity between two elements bonded into a compound by covalent bonds.
Select the statements that are true about electronegativity between elements and their type of bond?
If the difference in electronegativity is from 0.6 to 1.7, the bond will be polar and covalent.
If the electronegativity difference between elements X and Y is 2.1 the bond between the elements X-Y is?
ionic
How can a covalently bonded compound be recognized from its chemical formula?
You look up the elements involved on a periodic table, if there is a low electronegativity difference between them and if they are both nonmetals it is so. (Electronegativity decreases when you go left, increases when you go down)
Why do the elements S and O form a covalent bond?
If the electronegativity difference between two elements is above 1.7, then ionic bond is formed between these two. If the electronegativity difference is below 1.7, then they form covalent bond. In the case of sulphur and oxygen the electronegativity difference will be below 1.7
An ionic bond is most likely to form between two elements that have a?
... large difference in electronegativity.
A bond formed between two elements that have a very large difference in electronegativity is called?
ionic

KCl has a greater difference between the electronegativity of the two elements present.
A polar covalent bond is most likely to form between two elements that have a difference in electronegativity values of?
I believe it is if the difference in electronegativity is > 1.
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.
