Can a molecular compound have 3 elements?
In general, the elements that combine to form binary molecular compounds are both nonmetals. This contrasts with ionic compounds, which involve bonds between metal cations and nonmetal anions….Binary Molecular Compound Names.

Which is a property of a molecular compound?
The three main properties of a molecular substance include: low melting points, or a temperature that indicates when a solid substance changes to a liquid; and boiling points, or a temperature that indicates the point at which a liquid changes to a gas, or vapor; poor conductivity; and low solubility, which is a …
What is compound write the properties of compound?
A compound has unique properties that are distinct from the properties of its elemental constituents. One familiar chemical compound is water, a liquid that is nonflammable and does not support combustion. It is composed of two elements: hydrogen, an extremely flammable gas, and oxygen, a gas that supports combustion.
What are three properties of a covalent compound in the solid phase?
Covalent solids are held together by relatively weak intermolecular forces called van der Waals forces. Due to the weak intermolecular attractions, covalent solids generally have low melting points, low boiling points, and are often soft and pliable.
What are two major characteristics of molecular compounds?
Molecular Compounds have low melting and boiling point as compare to the Ionic Compounds. Molecular Compounds can be in any state, solid, liquid or gas at room temperature, whereas Ionic Compounds are always in solid state with forming crystalline appearance.
What are the characteristics of molecular substances?
Molecular substances are the substances which have two or more different atoms attached together. Molecular substances have weak intermolecular forces of attraction thus, they have low melting and boiling point. They have poor electrical conductivity as the bond formation in molecular compounds is covalent.
What is list of the properties of compounds?
The relative proportions of the elements in a compound are fixed.
What makes a molecular compound?
A molecular compound is formed when two or more atoms join together chemically through covalent bonds. Any compound will be considered as molecule that contains at least two different elements.
