Metallic and Ionic Bond

In metallic bonding, what holds the metal atoms together?

• Hydrogen bonds

• Delocalized electrons

• Ionic bonds

• Covalent bonds

What is the electron sea model in metallic bonding?

• The electron sea model involves covalent bonding between metal atoms.

• The electron sea model suggests that metals do not have any free electrons.

• The electron sea model describes metallic bonding as a sea of delocalized electrons moving freely throughout the metal structure.

• In the electron sea model, electrons are localized within specific atoms.

Why are metals good conductors of electricity?

• Sea of delocalized electrons

• Metals have no free electrons

• Metals have high resistance

• Metallic bonds are weak

What type of bonding involves the transfer of electrons from one atom to another?

In ionic bonding, what are formed between the positively and negatively charged ions?

• Hydrogen bonds

• Metallic bonds

• Ionic bonds

• Covalent bonds

How does the conductivity of ionic compounds compare to that of metals?

• Metals have lower conductivity compared to ionic compounds.

• Ionic compounds and metals have the same conductivity.

• Ionic compounds have higher conductivity compared to metals.

• Ionic compounds have lower conductivity compared to metals.

What is the main difference between metallic and ionic bonding?

• Metallic bonding involves the formation of covalent bonds, while ionic bonding involves the formation of metallic bonds.

• Metallic bonding involves the transfer of electrons to form ions, while ionic bonding involves the sharing of electrons in a lattice of metal atoms.

• Metallic bonding involves the sharing of electrons in a lattice of metal atoms, while ionic bonding involves the transfer of electrons to form ions.

• Metallic bonding involves the attraction between positive and negative ions, while ionic bonding involves the attraction between metal atoms.
