Which type of bond has an equal sharing of electrons?

• Polar Covalent 
• Non Polar Covalent
• Ionic
• Metallic

When electrons are shared unequally a/an ___________ bond is formed 

• ionic 
• hydrogen
• polar covalent 
• nonpolar covalent

The bonds in Na₂O are best described as 

• a.  covalent, because valence electrons are shared.
• covalent, because valence electrons are transferred
• ionic, because valance electrons are shared.
• ionic, because valance electrons are transferred.
