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.

Are melting points of covalent compounds high or low compared to ionic compounds?
Ionic compounds have strong electrostatic force of attraction and hence have higher melting points than covalent compounds.
What is the solubility of Covalent bonds?
Solubility of covalent bonds is usually high to low. Solubility for Ionic compounds is usually high.
What best describes an atom with low electronegativity?
Electronegativity is the ability of an atom to attract towards it the electron pair of a covalent bond. An atom with low electronegativity is poor at doing this. For instance, the electronegativity of bromine is less than that of chlorine.
What charge does the nitrogen family have when bonding?
In compounds with elemnts with low electronegativity compounds N3-, P3- etc are found.
What are two physical properties that differ between covalent and ionic bonds?
There are more than two. In general: Covalent compounds have low melting and boiling points while ionic compounds have high melting and boiling points. Ionic compounds are good conductors of electricity when melted, while covalent compounds are not. Ionic compounds are soluble in water, while covalent compounds are soluble in non-polar liquids. These are the essentials, but other differences exist. All of these are generalizations, exceptions do occur.
Is the boiling point of covalent compounds high or low?
high boiling point low melting point

Tantalum have a high or low electronegativity?
It electronegativity is 1.5

Electronegativity is the ability of an atom to attract towards it the electron pair of a covalent bond. An atom with low electronegativity is poor at doing this. For instance, the electronegativity of bromine is less than that of chlorine.
Which type of compound would have the lowest melting point?
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.

Does a small atomic radius correspond with a high or low electronegativity?
A small atomic radius corresponds more closely to a low electronegativity.
Is the electronegative of sulfur high or low?
Sulfur has a high electronegativity.
What properties do most covalent compounds have in common?
Most molecular compounds do not conduct electricity and have low melting points.
