REVIEW: Predicting Ionic Bonds & Formulas

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a non-metal.

Which element is most likely to form an ionic bond with chlorine?

Back

Sodium (Na) is most likely to form an ionic bond with chlorine.

Front

What is the characteristic of ionic compounds?

Back

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

Front

What is the charge of a potassium ion?

Back

The charge of a potassium ion (K⁺) is +1.

Front

What is the charge of an iodine ion?

Back

The charge of an iodine ion (I⁻) is -1.

Front

What is the significance of the octet rule in ionic bonding?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to the formation of stable ionic compounds.
