Ions are formed by one atom taking an electron or electrons from anothe atom. This forms individual charged particles -- ions which attract each other to form a relatively large crystaline structure. This is an ionic compound.
Moleculecs are formed by atoms which share electrons throught a strong bond which holds them together in very small individual structures called molecules. These may have weak attractions to other molecules but, like water, there is not a strong enough attraction to form solid crystal structures.
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.
Isomers.
Molecular compounds are composed of all types of elements. I think the answer you're going for is what type of BONDS are molecular compounds composed of. In which case, the answer would be covalant, however this can vary between polar and nonpolar covalant, that's what a molecular compound is made of, otherwise it's an ionic compound.
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.
Two compounds that have the same molecular formula but different structural formulas are isomers. Isomers are compounds with the same number and types of atoms but arranged differently. An example is ethanol (C2H6O) and dimethyl ether (C2H6O), both have the same molecular formula but different structural formulas.
the relationship between prefixes and molecular compounds is that, prefix are used to name molecular compounds.
When molecular compounds bond, they share electrons.
Because there are no compounds that aren't molecules/molecular. The question as posed is nonsense. Rephrase?
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).
Molecular (covalent) compounds are not dissociated in water.
Atoms are arranged in molecular compounds in groups.
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.
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.
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.
no
Yes, most molecular compounds do not contain metals. (The term "nonmetal" properly applies only to elements, not compounds.)
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.
