Understanding Chemical Bonds

What type of bond is formed when one atom pulls electrons from another, creating charged ions?

• Hydrogen bond

• Metallic bond

• Ionic bond

• Covalent bond

In an ionic bond, what happens to the electrons?

• They remain in the same atom.

• They are lost to the environment.

• They are transferred from one atom to another.

• They are shared equally between atoms.

How do covalent bonds differ from ionic bonds?

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

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

• Covalent bonds involve losing electrons, while ionic bonds involve gaining electrons.

• Covalent bonds involve gaining electrons, while ionic bonds involve losing electrons.
