What are some examples of ionic bonds?

Ionic bonds occur when electrons are transferred from one atom to another. A classic example is sodium chloride (table salt), where sodium donates an electron to chlorine.

Can you explain how sodium and chlorine form an ionic bond?

Sure! Sodium has one electron in its outer shell, while chlorine has seven. Sodium loses its electron, becoming a positively charged ion, and chlorine gains that electron, becoming negatively charged. They attract each other due to opposite charges.

Are there other examples besides sodium chloride?

Yes, other examples include magnesium oxide (MgO) and calcium fluoride (CaF2). In these compounds, magnesium and calcium also lose electrons to form positive ions, while oxygen and fluorine gain electrons to become negative ions.

What properties do ionic compounds have?

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved or molten.
