What else can I help you with?
Does covalent compounds have a high or low electronegativity?
In comparison with ionic bonds, the difference in electronegativities of elements in a covalent bond have a lower difference in electronegativities. A covalent bond occurs between two nonmetals that have a difference in electronegativities that is 1.7 or less. Usually an ionic bond has a difference in electronegativities that is greater than 1.7, but not always.
Atoms with electronegativity differences below 0.4 generally form covalent bonds.?
TRUE
What kind of elements generally make up covalent bonds?
Covalent bonds are typically formed by the sharing of electrons between two atoms. Atoms with similar electronegativities tend to form covalent bonds. Covalent bonds can be made up of nonmetals or metalloids in a compound.
What does a nonpolar covalent bond show about the electronegativities of its two atoms?
The electronegativities of two atoms are equal :)
Which substance has polar covalent bonds SO2 Cl2 N2 or CaO?
SO2 is the substance that has polar covalent bonds. This is because sulfur and oxygen have different electronegativities, resulting in an uneven sharing of electrons in the covalent bonds within the molecule.
How do you determine whether a compound with more than two elements such as Al2(SO4)3 is ionic or covalent?
When the difference between the electronegativities of two elements is in the range 0-2 (Pauling system) the bond is covalent; generally compounds between nonmetals are covalent.

What does a non polar covalent bond show about electronegativities of its two atoms?
The electronegativities of it's two atoms are similar.
What does a nonpolar covalent bond show about the electronegativities of its two atoms?
The electronegativities of two atoms are equal :)
Which substance has polar covalent bonds SO2 Cl2 N2 or CaO?
SO2 is the substance that has polar covalent bonds. This is because sulfur and oxygen have different electronegativities, resulting in an uneven sharing of electrons in the covalent bonds within the molecule.
Which substance is correctly paired with its type of bonding br2 polar covalent?
The pairing of Br2 with polar covalent bonding is incorrect. Br2 exhibits nonpolar covalent bonding due to the similar electronegativities of the two bromine atoms causing a symmetrical distribution of electrons, resulting in a nonpolar molecule.
Why does chemical formula help identify whether a substance is ionic or covalent?
Generally compounds formed between nonmetals are covalent.
How can the type of bond be predicted?
Ionic bond: the difference between electronegativities of the atoms is over 2.Covalent polar bond: the difference between electronegativities of the atoms is under 2.Covalent non-polar bond: the difference between electronegativities of the atoms is cca. zero
What is the the best way to predict covalent bonds?
The best way to predict covalent bonds is to consider the number of valence electrons in each atom and their electronegativities. Atoms with similar electronegativities tend to form nonpolar covalent bonds, while atoms with different electronegativities form polar covalent bonds. The octet rule can also be used to predict covalent bonding in many cases.
Is the bond formed between Si and C ionic polar covalent or nonpolar covalent?
The bond is polar covalent- the diffference in electronegativities is 0.65.
