what is the difference between simple covalent and giant covalent compounds?
148910
In terms of the structure, simple covalent substances are made up of molecules. These molecules are bonded together by a shared pair of electrons, which forms the strong covalent bond. ... Giant covalent substances, such as diamond, contain many strong covalent bonds in a 3D lattice structure.

Covalent compounds usually have low melting points except in case of molecules like diamonds and silica lattice. The boiling points of these covalent molecules is low as the force of attraction between the bonded atoms are held together by van der Waal forces. Covalent bonded compounds are usual...

Transition metals tend to form covalent bonds more easily than main group metals because transition metals are more electronegative than main group metals. Main group metals form bonds that are electrically neutral, whereas transition metals tend to form bonds that have an excess of negative ions.

Covalent compounds and coordination compounds essentially have bond pairs. They may or may not have lone pairs. The difference between bond pair and lone pair is that a bond pair is composed of two electrons that are in a bond whereas a lone pair is composed of two electrons that are not in a bond.

Covalent compounds are usually gaseous molecules at room temperature and pressure. They might also be liquids with low relatively low boiling points. These characteristics could be attributed to their weak intermolecular forces which hold these atoms together. However, we also have a lot of solid covalent compounds.

Covalent bonds are formed between two non-metals, whereas ionic bonds are formed between a metal and non-metal. Molecules formed by covalent bonds have a low melting point, whereas those with ionic bonds have a high melting point. The same relationship exists for boiling point.

Covalent compounds are formed on the basis of sharing electrons. When the electrons are shared within the bonds, there is no electrons available to conduct electricity - hence why covalent compounds are generally poor conductors of electricity.

Re: Difference between coordinate covalent and covalent bond Coordinate covalent bonds have one species donate both electrons to the forming the bond while usually covalent bonds have one electron come from each atom.

Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.

The difference between an ionic and a covalent bond is that a covalent bond is formed when two atoms share electrons. Ionic bonds are forces that hold together electrostatic forces of attractions between oppositely charged ions.

A single covalent bond is formed when two electrons are shared between the same two atoms, one electron from each atom. A double covalent bond is formed when four electrons are shared between the same two atoms, two electrons from each atom.

The most important difference between ionic and molecular compounds lies in their formation. Ionic compounds are formed by the transfer of electrons while molecular compounds are formed by the sharing of electrons. Molecular compounds are also called covalent compounds.

The physical and chemical properties of covalent compounds tend to vary much more than they do for ionic compounds. These compounds may be solids, liquid or gases at room temperature. They are not usually electrically conductive. Polar covalent compounds are soluble in water but nonpolar ones are not.

There are two different types of covalent structure, depending on how the atoms bond with each other. Covalent molecular structures consist of molecules on their own. They have low melting and boiling points. ... Covalent network structures are made from a network of repeating lattices of covalently bonded atoms.

Compounds with covalent bonds may be solid, liquid or gas at room temperature depending on the number of atoms in the compound. ... Since most covalent compounds contain only a few atoms and the forces between molecules are weak, most covalent compounds have low melting and boiling points.

These molecules are bonded together by a shared pair of electrons, which forms the strong covalent bond. ... As a result, simple covalent substances generally have low melting/boiling points. Giant covalent substances, such as diamond, contain many strong covalent bonds in a 3D lattice structure.
