Guida verificata passo dopo passo1
Understand that electrons in an atom are arranged in energy levels or shells around the nucleus.
Recognize that the outermost energy level of an atom contains electrons that are involved in chemical bonding and reactions.
Identify that these electrons in the outermost shell are called \(\textbf{valence electrons}\).
Differentiate valence electrons from core electrons, which are those in inner shells and not typically involved in bonding.
Note that terms like bonding electrons refer to valence electrons specifically involved in bonds, but the general term for electrons in the outermost shell is \(\textbf{valence electrons}\).
