__________ can be both an atom and a molecule. A) Hydrogen A) Helium
Murrr4er [49]

Answer:

Hydrogen

Explanation:

Because helium is a noble gas with a full valence shell, it does not bond with other atoms readily. This means that it cannot be a molecule. However, hydrogen can bond with a lot of things, because of its unique property of having just one electron, meaning that it can donate or accept one, making it able to easily become a molecule. Hope this helps!
