Do ionic or covalent bonds hold molecules in a crystal of a molecular substance in place?
Aajulyereneau
It depends on the nature of the molecule. In the case of ionic compounds, ionic bond between the ions will hold the crystal together. In the case of covalent compounds, covalent bond will hold the molecules in the crystal together.

What are two ways that crystal and molecular structures affect the properties of ionic and covalent compounds?
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.
Why do ionic and polar covalent compounds form chrystals?
Ionic compounds form a crystal lattice. Covalent compounds, polar AND non-polar, giant molecule AND molecular can form crystals. Molecular covalent compunds form regular lattices where the molecules are packed in a regular way.
Why do solid compounds have higher melting points than solid covalent compounds?
Solid molecular covalent compounds consist of molecules held together with intermolecular forces, such as dipole dipole interactions and london dispersion forces.Covalent compounds which are giant molecules such as found in diamond or silica are in fact high melting as the strong covalent bonds have to be broken to break down the crystal.Ionic compounds are generally high melting as the strong ionic bonds have to be broken to break down the crystal lattice.
What is type of bonding and the crystal structure?
There are several types of bonds that can have a crystallized structure. These include ionic bonds, covalent bonds, and metallic bonds. The crystal structure is an arrangement of atoms and molecules.
Why do simple molecular structures have low melting points?
Because although the covalent bonds between the elements are strong, there are only weak forces between the molecules so they have low melting points
Which force binds different molecules of sugar together in a sugar crystal?
covalent bonds.
Can you compare and contrast the 4 types of crystals?
Covalent, Metallic, and Ionic crystals have high melting points and densities, but molecular crystals tend to be soft and has a lower melting point. Covalent crystal=covalent bond and Ionic crystal=ionic bond.

What is giant molecular crystal?
A giant molecular crystal is a type of crystal in which the repeating unit is a large molecule or a complex network of molecules. These crystals have a high degree of structural order and can exhibit unique physical and chemical properties due to the arrangement of the molecules within the crystal lattice. Examples of giant molecular crystals include diamond, graphite, and fullerenes.
Is iodine crystal an ionic or molecular crystal?
it has molecular crystals

What is CO ionic or molecular?
CO is molecular
Note that ionic substances melt at higher temperatures than metallic substances and metals melt at higher temperatures than molecular substances?
If the question is "Why do etc." then: Ions in an ionic crystal are held together by ionic bonds aka direct electrostatic interaction, a fairly strong force. Metal atoms in a metal are held together by the metallic bond, which is weaker than an ionic bond or covalent bond but still pretty strong. Molecules in a molecular crystal are held together by covalent bonds internally, but the forces between molecules are at best relatively weak interactions (London or van der Waals type forces).
