Ionic Bonding Quiz

What happens to an atom when it forms an ionic bond?

• Shares electrons equally with another atom.

• Does not change its electronic configuration.

• Gains or loses electrons to achieve a full outer shell.

• Gains neutrons to become more stable.

Which of the following is a property of ionic compounds?

• High melting and boiling points

• Low melting and boiling points

• Poor electrical conductivity in solid state

• Both A and C

What is the structure formed by ionic compounds?

• Covalent network

• Molecular structure

• Crystalline lattice

• Polyatomic ion

What primarily determines the strength of an ionic bond?

• The size of the ions

• The charge of the ions

• The distance between the ions

• Both B and C

Which of the following is an example of an ionic bond?

• NaCl

How are ions formed from neutral atoms?

• By sharing electrons with other atoms

• By gaining or losing protons

• By gaining or losing electrons

• Changing the number of neutrons

Why do ionic compounds have high melting and boiling points?

• Due to weak forces between the ions

• Due to the strong ionic bonds between the ions

• Because they are made of metals

• Because they are made of non-metals

• They are poor conductors.

• They are superconductors.

• Their conductivity does not change with the state.
