Exploring Ionic Compounds: Structure, Properties, and Formulas

What is the primary process involved in the formation of an ionic bond?

• Transfer of protons from a non-metal to a metal

• Sharing of protons between atoms

• Transfer of electrons from a metal to a non-metal

• Sharing of electrons between atoms

In a lattice structure of an ionic compound, how are the ions arranged?

• In pairs of positive and negative ions

• Alternating positive and negative ions in all directions

• In a linear chain

• Randomly scattered

Which diagram is used to represent ionic compounds by showing ions and the bonds between them?

• Lewis dot structure

• Ball and stick diagram

• Electron cloud diagram

• Molecular orbital diagram

Why do ionic compounds have high melting and boiling points?

• Because they are always in a solid state

• Because they are made of large molecules

• Due to the strong ionic bonds that require a lot of energy to break

• Due to the presence of free electrons

Under what conditions can ionic compounds conduct electricity?

• When they are in powdered form

• When they are in gaseous form

• When they are melted or dissolved in water

• When they are in solid form
