Unit 6: Ionic Bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions that attract each other.

Front

What is the overall charge of an ionic compound?

Back

The overall charge of an ionic compound is 0, meaning it is electrically neutral.

Front

What is the charge of a copper ion in Copper (II) Oxide?

Back

The charge of a copper ion in Copper (II) Oxide is +2.

Front

What is the formula for sulfide?

Back

The formula for sulfide is S^-2.

Front

What is the chemical formula for the compound formed from calcium and sulfur?

Back

The chemical formula for the compound formed from calcium and sulfur is CaS.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell of eight electrons, achieving a stable electron configuration similar to that of noble gases.

Front

What is the charge of a calcium ion?

Back

The charge of a calcium ion is +2.

Front

How do you determine the formula of an ionic compound?

Back

To determine the formula of an ionic compound, combine the symbols of the ions involved, ensuring that the total positive charge equals the total negative charge.

Front

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

Back

The octet rule is significant in ionic bonding because it explains why atoms transfer electrons to achieve stable electron configurations, leading to the formation of ionic compounds.

Front

What is the role of electronegativity in ionic bonds?

Back

Electronegativity is the tendency of an atom to attract electrons; in ionic bonds, a highly electronegative atom will attract electrons from a less electronegative atom, resulting in the formation of ions.
