What are Ionic Bonds?

The video tutorial explains ionic bonds, which are formed through the transfer of electrons between atoms, resulting in oppositely charged ions that are electrostatically attracted to each other. Examples include sodium chloride, magnesium oxide, and calcium chloride, where electron transfer leads to the formation of ionic compounds with balanced charges. The tutorial emphasizes the importance of charge balance in forming neutral ionic compounds.

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

• They are shared between atoms.

• They are transferred from one atom to another.

• They are destroyed.

• They remain in their original atoms.

In the formation of sodium chloride, what happens to the sodium atom?

• It shares an electron.

• It remains unchanged.

• It loses an electron.

• It gains an electron.

How many electrons does magnesium transfer to oxygen to form magnesium oxide?

• One electron

• Four electrons

• Three electrons

• Two electrons

What is the result of calcium losing two electrons in the formation of calcium chloride?

• It forms a calcium ion and two chloride ions.

• It forms a calcium ion and a chloride ion.

• It forms two chloride ions.

• It forms two calcium ions.

Why must the charges in an ionic compound be balanced?

• To make the compound magnetic.

• To ensure the compound is stable.

• To make the compound soluble in water.

• To give the compound a neutral charge.
