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.
In which state do ionic compounds usually exist at room temperature?
Ionic compounds typically exist as solids at room temperature, regardless of the state of matter of other compounds. This is because ionic compounds have strong electrostatic interactions between positive and negative ions, which hold them together in a solid crystal lattice structure.
Do ionic compounds form crystals?
Yes, ionic compounds form crystals as a result of the regular arrangement of positive and negative ions in a repeating pattern. This arrangement is known as a crystal lattice structure and is responsible for the distinct shape and properties of many ionic compounds.
When compounds that are formed by ionic bonds decompose the products are usually what?
When compounds formed by ionic bonds decompose, the products are typically the separate ions that made up the original compounds. This decomposition process usually occurs when the ionic compound is subjected to heat, electricity, or chemical reactions that break the bonds holding the ions together.
Are ionic compounds usually liquids or gasses?
Ionic compounds are typically solid at room temperature. They have high melting and boiling points due to the strong electrostatic forces between the ions in the crystal lattice. However, there are some exceptions where ionic compounds can be liquids, like molten salts or certain ionic liquids.
Is salt a substance of mixtures?
salts are usually ionic compounds.
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.

Are ionic compounds usually gases or liquids?
Ionic compounds are usually solids at room temperature, rather than gases or liquids. This is because they have strong electrostatic forces holding their ions together in a stable lattice structure.
When compounds that are formed from ionic bonds decompose the products are usually .?
When compounds formed from ionic bonds decompose, the products are usually individual ions that were part of the original compound. This is because ionic bonds are formed between ions of opposite charge, and when the bond is broken, these ions are released.
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.
Give the properties of ionic compounds?
Ionic compounds are typically formed between a metal and a nonmetal. They have high melting and boiling points, are soluble in water, and conduct electricity when dissolved in water or as a molten state due to the presence of free ions. Additionally, they tend to have a crystalline structure and are usually hard and brittle.
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.
