3.3 Extension - 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 formed when one atom donates an electron to another.

What is the formula for magnesium sulfate?

Back

MgSO₄

Front

What is an ion?

Back

An ion is a charged particle that has gained or lost one or more electrons.

Front

How can ionic compounds conduct electricity?

Back

Ionic compounds can conduct electricity when dissolved in water, as the ions are free to move.

Front

What is the correct name for CaBr₂?

Back

Calcium Bromide

Front

What is the formula for barium nitride?

Back

Ba₃N₂

Front

What are cations and anions?

Back

Cations are positively charged ions, while anions are negatively charged ions.

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.

Front

What is the difference between a molecule and an ion?

Back

A molecule is a group of atoms bonded together, while an ion is a single atom or group of atoms that has a net charge due to the loss or gain of electrons.

Front

What is the role of electronegativity in ionic bonding?

Back

Electronegativity is the tendency of an atom to attract electrons; in ionic bonding, a significant difference in electronegativity between two atoms leads to the transfer of electrons.
