How do ionic and molecular compounds differ in physical properties?
Ionic compounds have higher melting and boiling points than molecular compounds due to the strong electrostatic forces between ions. Ionic compounds are usually solid at room temperature, while molecular compounds can be solid, liquid, or gas. Ionic compounds conduct electricity when dissolved in water, while molecular compounds do not.
Why can ionic compounds conduct electricity but molecular compounds usually can not?
Ionic compounds can conduct electricity because the ions in the solid state can move and carry electric charge. In contrast, molecular compounds usually do not conduct electricity because they do not dissociate into ions in solution or in the solid state, resulting in no free charge carriers to conduct electricity.
The properties of both ionic and molecular compounds are related to the?
The properties of both ionic and molecular compounds are related to their chemical bonding. Ionic compounds have strong electrostatic interactions between positively and negatively charged ions, resulting in high melting points and conductivity when dissolved in water. Molecular compounds have covalent bonds between atoms and tend to have lower melting points, are usually not conductive, and can exist as gases, liquids, or solids at room temperature.
Are covalent molecular compounds ductile?
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.
What is the difference between molecular compounds and molecular element?
Molecular compounds are made up of multiple different elements bonded together, while molecular elements are made up of the same type of element bonded together. Molecular compounds have multiple types of atoms, while molecular elements have only one type of atom.
Are molecular compounds usually non-metals?
Yes, most molecular compounds do not contain metals. (The term "nonmetal" properly applies only to elements, not compounds.)

Ionic compounds are usually solid at room temperature, while molecular compounds can be solid, liquid, or gas. Ionic compounds conduct electricity when dissolved in water, while molecular compounds do not.
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.
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.
Is a brittle compound a molecular compound?
No, a brittle compound does not necessarily indicate it is a molecular compound. Brittle compounds can be either molecular or ionic, depending on their chemical bonding. Brittle molecular compounds typically have covalent bonds, while brittle ionic compounds have ionic bonds.
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.
Why can ionic compounds conduct electricity but molecular compounds usually can not?
Ionic compounds can conduct electricity because the ions in the solid state can move and carry electric charge. In contrast, molecular compounds usually do not conduct electricity because they do not dissociate into ions in solution or in the solid state, resulting in no free charge carriers to conduct electricity.
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?
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 aqueous solutions of ionic and molecular compounds differ?
Aqueous solutions of ionic compounds consist of ions dissolved in water, while solutions of molecular compounds consist of intact molecules dispersed in water. Ionic compounds dissociate into ions in water, leading to electrolytic behavior, while molecular compounds usually do not conduct electricity in solution unless they ionize.
How are atom arranged in molecular compounds?
Atoms are arranged in molecular compounds in groups.
