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 shell or 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 found in inner shells and are not typically involved in bonding.
Note that bonding electrons are valence electrons specifically involved in forming bonds, and free electrons refer to electrons not bound to an atom.
