What else can I help you with?
Why is it that only molecular compounds can have a molecular formula?
Because there are no compounds that aren't molecules/molecular. The question as posed is nonsense. Rephrase?
How is molecular weight and thermal stability related?
They are not related. Thermal stability depends much more on the nature of the bonds in the compound, not the molecular weight.Boiling and melting points do generally reflect molecular weight (both go up with increasing mass), but thermal stability usually refers to chemical decomposition rather than physical changes such as melting or boiling.There are very light and very stable compounds (carbon dioxide is one), and there are very big and stable compounds (polymers), and there are very light unstable compounds (hydrogen gas) and very heavy unstable compounds (TNT isn't huge, but fairly large...).
Are molecular compounds formed from semimetals?
Yes, molecular compounds can be formed from semimetals. These compounds result from the bonding of semimetal atoms to form molecules, often through sharing electrons in covalent bonds. Examples of molecular compounds with semimetals include carbon monoxide (CO) and boron trifluoride (BF3).
How do you differentiate simple molecular compounds and giant molecular compounds?
Simple molecular compounds have discrete molecules held together by weak intermolecular forces, while giant molecular compounds have repeating units bonded together by strong covalent bonds. Simple molecular compounds typically have low melting and boiling points and are often gases or liquids at room temperature, while giant molecular compounds tend to have high melting and boiling points and are usually solids at room temperature.
How are molecular compounds held together?
Molecular compounds are held together by covalent bonds, which are formed when atoms share electrons to achieve a stable electron configuration. These bonds involve the sharing of electron pairs between atoms, creating a strong bond that holds the atoms together in a molecule.
What are the smallest units of covalent molecular compounds called?
The smallest units of covalent molecular compounds are called molecules. They are formed when atoms share electrons to achieve a stable electron configuration.
Are ammonia and lime covalent compounds?
No, ammonia (NH3) is a covalent compound, while lime (CaO) is an ionic compound. Covalent compounds form when nonmetals combine, sharing electrons to achieve stability. Ionic compounds form when a metal and a nonmetal combine, transferring electrons to achieve stability.
Are non aromatic compounds stable or unstable?
Non-aromatic compounds can be stable or unstable, as stability is determined by factors such as bond strength, molecular structure, and energy content. Non-aromatic compounds can exhibit varying degrees of stability, depending on their specific chemical composition and environment.
What is the relationship between prefixes and molecular compounds?
the relationship between prefixes and molecular compounds is that, prefix are used to name molecular compounds.
How do molecular compounds bond?
When molecular compounds bond, they share electrons.

How are atom arranged in molecular compounds?
Atoms are arranged in molecular compounds in groups.
How are the properties of molecular compounds different from those of ionic cmpounds?
Molecular (covalent) compounds are not dissociated in water.
Why are electrons shared in molecular compounds?
The sharing of electrons is what makes them molecular compounds. If they didn't share, then they would be ionic compounds. So, depending on what atoms or elements are bonding together, you will have sharing or not. Whether they share or not is more complicated, but has to do with electronegativity and electron configurations.
Are molecular compounds made up of metals or nonmetals?
Molecular compounds are typically made up of nonmetals. Metals tend to form ionic compounds with nonmetals, whereas nonmetals tend to share electrons with other nonmetals, resulting in the formation of molecular compounds through covalent bonding.
