ionic compounds

What is an ionic compound?

An ionic compound is a chemical compound formed by electrostatic forces (ionic bonds) between oppositely charged ions, typically a metal cation and a nonmetal anion, resulting from the transfer of electrons.

What are some key physical properties of ionic compounds?

Ionic compounds typically have high melting and boiling points, are hard and brittle, and conduct electricity when molten or dissolved in water, but not in solid form.

Why do ionic compounds have high melting points?

Due to the strong electrostatic forces (ionic bonds) between oppositely charged ions in their crystal lattice, which require a large amount of energy to overcome.

What are some general properties of small molecules?

Small molecules typically have lower melting and boiling points compared to ionic compounds, are often gases or liquids at room temperature, and do not conduct electricity.

What type of bonding is usually found in small molecules?

Small molecules are typically formed by covalent bonds, where atoms share electrons to achieve stable electron configurations.
