Ionic Bonding Through Visual Representation and Electron Transfer

The video tutorial explains ionic bonding, which occurs between metals and nonmetals. It describes how metals lose electrons to become positive ions, while nonmetals gain electrons to become negative ions, resulting in an attraction called ionic bonding. The tutorial provides detailed examples of ionic bonding in sodium chloride and magnesium oxide, illustrating electron transfer and the formation of ions. It concludes with tips for drawing ionic bonds and encourages practice for better understanding.

What happens to a metal atom during ionic bonding?

• It loses electrons and becomes a negative ion.

• It loses electrons and becomes a positive ion.

• It gains electrons and becomes a negative ion.

• It gains electrons and becomes a positive ion.
