In the context of ionic bonding, what is a cation?

• An electron donor

• A neutral atom

• A positively charged ion

• A negatively charged ion

How do covalent bonds differ from ionic bonds?

• Covalent bonds are weaker than ionic bonds

• Covalent bonds only occur in metals

• Covalent bonds do not involve electrons

• Covalent bonds involve sharing electrons, while ionic bonds involve transferring electrons

What type of bond is formed when two atoms share electrons?

• Ionic bond

• Metallic bond

• Covalent bond

• Hydrogen bond
