What are outer shell electrons referred to as?
Core electrons
Valence electrons
Bonding electrons
Free electrons
The correct answer is: Valence electrons
The term "valence electrons" specifically refers to the outer shell electrons of an atom. These electrons are crucial because they are involved in forming chemical bonds and determining the chemical properties of an element. Valence electrons occupy the highest energy levels and are the electrons that participate in reactions, allowing atoms to connect with each other to form compounds. Understanding the role of valence electrons is essential in fields like chemistry and nursing, especially when considering how substances interact within the body or when administering medications. In contrast, core electrons are those found deeper within the atom and do not typically participate in bonding or reactions. Bonding electrons are a subset of valence electrons that are specifically involved in bonding interactions, while free electrons are not bound to any particular atom and can move freely, as seen in conductivity. Each of these alternative terms reflects a different concept related to atomic structure.
