What covalent bonds are most polar?
Bonds between two nonmetals that differ in electronegativity (EN) are usually polar. Electronegativity is the tendency of an atom to attract electrons. Nonmetals with EN differences of 0.5-1.6 form polar covalent bonds. The greater the difference, the more polar. If the EN difference is
How can you tell that ionic bonding will placebetween metals and non metals?
Most of the time the bond between a metal and a nonmetal is ionic. However, there are some exceptions, such as BeCl2, which is covalent. The difference in electronegativity determines what kind of bond will form. Metals and nonmetals with a difference in electronegativity of >1.6 are considered to have an ionic bond.
Why covalent bond generally forms between atoms of non metal?
The electronegativity difference between nonmetals is relatively small, so such compounds are nearly always covalent. On the other hand the electronegativity difference between a metal and a nonmetal is often fairly large, so metal-nonmetal compounds are usually ionic.
Is Hydrogen sulfide covalent or ionic?
It is covalent due to the small electronegativity difference between hydrogen and sulfur.
What is the electronegativity equation used to calculate the difference in electronegativity between two atoms in a chemical bond?
The electronegativity equation used to calculate the difference in electronegativity between two atoms in a chemical bond is the absolute difference between the electronegativity values of the two atoms. This is represented as A - B, where A and B are the electronegativity values of the two atoms.
What type of bond is between Metals with nonmetals of differing electronegativities?
If the difference in electronegativity between the metal and the non metal is above 1.7, then ionic bond is formed. If the difference in electronegativity between the metal and the non metal is below 1.7, then polar covalent bond is formed.

It is covalent due to the small electronegativity difference between hydrogen and sulfur.
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)
What is the electronegativity equation used to calculate the difference in electronegativity between two atoms in a chemical bond?
The electronegativity equation used to calculate the difference in electronegativity between two atoms in a chemical bond is the absolute difference between the electronegativity values of the two atoms. This is represented as A - B, where A and B are the electronegativity values of the two atoms.
What values best classifies a bond between 2 atoms as being covalent?
An electronegativity difference of less that 1.7 between the atoms
What type of bond has high electronegativity?
It depends on the difference in electronegativity between the two atoms. If the EN difference between two atoms is less than 0.5,the bond is nonpolar covalent. If the EN difference between the two atoms is between 0.5 and 1.6, the bond is polar covalent. If the EN difference between the atoms is greater than 2.0, the bond is ionic. If the EN difference is between 1.6 and 2.0, and if a metal is involved, then the bond is considered ionic. If only nonmetals are involved, the bond is considered polar covalent.

Which bond has the greatest ionic charcter?
A bond between elements with a large difference in electronegativity will have the greatest ionic character. For example, the bond between a metal and a nonmetal (e.g. NaCl) will have a high ionic character compared to a bond between two nonmetals (e.g. H2O).
What will you look for to know if a compound is ionic or covalent?
An ionic compound is when the an atom gives away or receives electrons to become stable. A covalent compound is when the atoms share electrons to become stable.It is a Ionic bond because it is between nonmetals and metal
What is the electronegativity difference between Mg and Br .?
The electronegativity difference between Mg and Br is approximately 1.0. Mg has an electronegativity value of around 1.2, while Br has an electronegativity value of around 2.8. This difference in electronegativity indicates that a bond between Mg and Br would have a somewhat polar character.
