Is SO a molecular or ionic solid?
SO, known as sulfur monoxide, is a molecular solid. It consists of covalent bonds between sulfur and oxygen atoms. In contrast, ionic solids are composed of ions held together by electrostatic forces.
Why do molecular solids have lower boiling points than ionic solids?
Molecular solids have lower boiling points than ionic solids because the intermolecular forces between molecules in a molecular solid are weaker than the electrostatic forces between ions in an ionic solid. As a result, less energy is required to break apart the molecular interactions and transition to the gaseous phase in molecular solids compared to ionic solids with stronger ionic bonds.
Which solid is more likely to have the lowest melting point an ionic solid or molecular solid?
A molecular solid is more likely to have a lower melting point than an ionic solid. This is because molecular solids are held together by weaker intermolecular forces such as van der Waals forces, while ionic solids have strong electrostatic forces between ions.
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.
How do you determine if a solid is a ionic compound or a molecular solid?
One way to determine if a solid is an ionic compound or a molecular solid is by looking at the elements present in the compound. Ionic compounds are formed between a metal and a nonmetal, resulting in electrostatic attraction between ions. Molecular solids are formed by covalent bonds between nonmetal atoms, forming discrete molecules held together by intermolecular forces. You can also analyze the compound's properties, such as melting point and conductivity, to help identify its type.
What could you do to determine whether an unknown solid is an ionic compound or a molecular solid?
In the laboratory you could determine if a solid has an ionic bond or a metallic bond by trying to run a current through it. Metal solids have delocalized electrons and conduct electricity well. Ionic solids will not conduct electricity unless dissolved.
What happens to the particles of a ionic solid and a molecular solid when each mixes with water?
When an ionic solid mixes with water, the particles of the solid dissociate into separate ions, which then become solvated by the water molecules. In contrast, when a molecular solid mixes with water, the solid molecules remain intact and may dissolve or form a solution depending on the intermolecular forces between the molecules and water.
Ionic solid harder than molecular solids?
Ionic solids are typically harder than molecular solids because ionic bonds are stronger than intermolecular forces found in molecular solids. The ionic bonds in ionic solids result from the attraction between positively and negatively charged ions, contributing to their higher hardness compared to molecular solids, which are held together by weaker intermolecular forces.
Is Zn molecular or ionic or neither?
Zinc (Zn) is an elemental metal and is not considered molecular or ionic. It exists as individual atoms in its solid metallic form.
How do you know a compound is ionic or molecular?
An ionic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state . A molecular compound, on the other hand, is a pure substance that is formed from nonmetals. It has a fairly low melting point, and cannot conduct electricity regardless of state. Another important difference between the two is that an ionic compound is a crystalline solid at standard ambient temperature and pressure (SATP), whereas a molecular compound can be in a solid, gas or liquid state at SATP.
Is S(s) is ionic or molecular and atomic solid?
Sulfur is a chemical element.
Is a white crystalline solid ionic or molecular?
"White crystalline" is not a criterion in this case.
