Understanding Ionic Bonding Concepts

What is the definition of ionic bonding?

• A type of chemical bond where atoms share electrons equally.

• A type of chemical bond where atoms transfer electrons from one to another.

• A type of chemical bond where atoms share electrons unequally.

• A type of chemical bond where atoms do not interact at all.

Which of the following is a property of ionic compounds?

• They have low melting points.

• They conduct electricity when dissolved in water.

• They are usually gases at room temperature.

• They are poor conductors of electricity in any state.

How are ionic bonds formed?

• By the sharing of electrons between two non-metals.

• By the transfer of electrons from a metal to a non-metal.

• By the sharing of electrons between two metals.

• By the transfer of electrons from a non-metal to a metal.

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

• NaCl

What is the typical state of ionic compounds at room temperature?

• Gas

• Liquid

• Solid

• Plasma

Why do ionic compounds have high melting points?

• Because of the weak forces between ions.

• Because of the strong electrostatic forces between ions.

• Because they are made of large molecules.

• Because they are gases at room temperature.

What happens to the electrons in an ionic bond?

• They are shared equally between atoms.

• They are transferred from one atom to another.

• They are shared unequally between atoms.

• They remain with the atom they started with.

Which of the following best describes the electrical conductivity of ionic compounds in solid state?

• Good conductors

• Poor conductors

• Excellent insulators

• Superconductors

What is the charge on an ion that has lost two electrons?

• 2+

• 2-

• 1+

• 1-

Which of the following statements is true about the solubility of ionic compounds in water?

• All ionic compounds are insoluble in water.

• Most ionic compounds are soluble in water.

• Ionic compounds are only soluble in organic solvents.

• Ionic compounds dissolve in water to form non-conductive solutions.
