Ionic Bonding

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 nonmetal.

Front

What is a cation?

Back

A cation is a positively charged ion that has lost one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that has gained one or more electrons.

What is the charge of aluminum in aluminum oxide (Al2O3)?

Back

The charge of aluminum in aluminum oxide is +3 (Al⁺³).

Front

What is the charge of sulfur in sulfide (S^2-)?

Back

The charge of sulfur in sulfide is -2.

Front

How do you determine the formula of an ionic compound?

Back

To determine the formula of an ionic compound, balance the total positive and negative charges of the cations and anions.

Front

What is the formula for the ionic compound formed from sodium (Na⁺¹) and chloride (Cl^-1)?

Back

The formula is NaCl.

Front

What happens to electrons during the formation of an ionic bond?

Back

During the formation of an ionic bond, electrons are transferred from the metal to the nonmetal.

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 stability.

Front

What type of elements typically form ionic bonds?

Back

Ionic bonds typically form between metals (which lose electrons) and nonmetals (which gain electrons).
