Understanding Ionic Bonds

What is the primary reason atoms form ionic bonds?

• To change their atomic number

• To achieve a stable electron configuration

• To increase their atomic mass

• To become radioactive

How do ionic compounds maintain neutrality?

• By forming covalent bonds

• By having more electrons than protons

• By balancing the positive and negative charges

• By having an equal number of protons and neutrons

Which of the following is a characteristic of ionic compounds?

• They have a low melting point

• They are composed of metals and nonmetals

• They are formed by the sharing of electrons

• They are composed of only nonmetals

What happens to the size of sodium and fluorine ions after electron exchange?

• Sodium becomes larger, and fluorine becomes smaller

• Both ions become larger

• Sodium becomes smaller, and fluorine becomes larger

• Both ions become smaller

What determines the crystalline structure of ionic compounds?

• The size and charge of the ions

• The color of the ions

• The temperature of the environment

• The speed of electron exchange
