Exploring Ionic Bonding and Lewis Structures

This video tutorial introduces chemical bonding, focusing on ionic bonding. It explains how atoms seek full valence shells, leading to electron transfer. Sodium is used as an example of a metal forming a cation by losing an electron, while chlorine forms an anion by gaining an electron. The video also covers the properties of ionic compounds, such as forming crystal lattices and conducting electricity when dissolved in water. Magnesium and chlorine bonding is discussed, illustrating electron transfer and the formation of ionic bonds.

Why do atoms strive to have a full valence shell?

• To increase their size

• To achieve stability

• To become more reactive

• To lose all their electrons

What happens to sodium when it loses its last valence electron?

• It gains an electron

• It becomes a positive ion

• It becomes a negative ion

• It remains neutral

What is a cation?

• An electron

• A positive ion

• A neutral atom

• A negative ion

Why are cations smaller than their original atoms?

• They gain more protons

• They lose an entire principal energy level

• They gain more electrons

• They become neutral

What happens to chlorine when it gains an electron?

• It loses a proton

• It becomes a negative ion

• It becomes a neutral atom

• It becomes a positive ion

What is an anion?

• A neutral atom

• A negative ion

• A positive ion

• A proton

How do sodium and chlorine form an ionic bond?

• By gaining protons

• By sharing electrons

• By transferring electrons

• By losing protons

What is the general term for any ionic solid?

• Molecule

• Salt

• Non-metal

• Metal

What is a characteristic property of ionic compounds?

• Non-conductive

• Soft and malleable

• Low melting points

• High melting points

When do ionic compounds conduct electricity?

• When they are solid

• When they are dissolved in water or molten

• When they are in gaseous form

• When they are mixed with sugar
