The cubic shape of sodium chloride crystals is a result of how the ions form crystals.
But Im Still Reading The Rest
Notice how each positive ion is
surrounded by six negative ions, and
each negative ion is surrounded by six
positive ions. This regular arrangement
gives the sodium chloride
crystal its characteristic cubic
shape. You can see this distinctive
crystal shape when you look
at table salt crystals through a
magnifying glass.
The diverse properties of covalent compounds arise from the varying strengths of the covalent bonds between atoms, different molecular structures, and the types of atoms involved. Factors like bond polarity, molecular shape, and intermolecular forces can all contribute to the wide range of physical and chemical properties exhibited by covalent compounds.
No, covalent molecular compounds are typically not ductile because they are made up of individual molecules held together by covalent bonds. These compounds have a molecular structure that does not allow for the same type of malleability or flexibility as metallic or ionic compounds.

Yes, a covalent compound is a type of molecular compound. Covalent compounds are formed by sharing electrons between atoms, leading to the formation of molecules. These compounds typically consist of nonmetals bonded together.
For the elements hydogen and the second period, C, N, O there is possibility for strong pi bonding, with carbon formation of long chains, and with the electronegative element O the formation of hydrogen bonds. All of these elemnts are non-metals and the bonds are almost exclusively covalent.

Molecular (covalent) compounds are not dissociated in water.

In a covalent bond the electrons are shared between atoms.
Covalent Bonds
Most covalent compounds have relatively low melting and boiling points, as they are held together by weak intermolecular forces. They are usually insoluble in water but soluble in nonpolar solvents. Covalent compounds tend to be nonconductors of electricity in their solid form.

Covalent substances do not conduct electricity because they are sharing electrons, hence they are in a fixed position and are not able to move around and contribute to movement of the electric current.
Covalent compounds exhibit isomerism because they have the same chemical formula but different structural arrangements of atoms. This results in different physical and chemical properties for each isomer. Isomerism in covalent compounds is often due to differences in the connectivity or spatial arrangement of atoms within the molecule.
Usually, however, the are a few covalent compounds, such as silicon dioxide (SiO2) that form covalent networks rather than molecules.
