A covalent bond in which one atom contributes both bonding electrons is called

• a coordinate covalent bond

• an ionic bond

• a metallic bond

• a cooperative bond

NH₄⁺ would be classified as a

A shared pair of electrons creates

• A triple bond

• An ionic bond

• A double bond

• A single bond

In order to achieve noble gas configuration, what happens with the electrons in covalent bonds?

• Electrons are gained or lost to create ions

• Electron pairs are sharedf

• Electrons are lost to space

• No one is sure
